[PATCH 0/2] ASoC: (SOF) topology: Regression fixes for next
by Peter Ujfalusi 03 Feb '23

03 Feb '23

Hi, Today I came across two regressions in next with SOF: The topology would not load with a failure of creating playback DAI the first patch is fixing this which was caused by a missing 'else' in the patch After fixing the topology loading, the module unloading caused kernel panic. The second patch is correcting that which is I likely caused by copy-paste to set wrong unload callback for the graph element. With these patches applied SOF is working on next and modules can be unloaded Regards, Peter --- Peter Ujfalusi (2): ASoC: SOF: topology: Add missed "else" in sof_connect_dai_widget ASoC: topology: Set correct unload callback for graph type sound/soc/soc-topology.c | 2 +- sound/soc/sof/topology.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) -- 2.39.1

Change the condition to check for SND_SOC_SOF_INTEL_SOUNDWIRE to be a boolean rather than a tristate expression in order to propagate this as intended.

[PATCH] tree-wide: trivial: s/ a SPI/ an SPI/
by Tudor Ambarus 03 Feb '23

03 Feb '23

The deciding factor for when a/an should be used is the sound that begins the word which follows these indefinite articles, rather than the letter which does. Use "an SPI" (SPI begins with the consonant letter S, but the S is pronounced with its letter name, "es."). Used sed to do the replacement: find . -type f -exec sed -i "s/ a SPI/ an SPI/g" {} \; Signed-off-by: Tudor Ambarus <tudor.ambarus(a)linaro.org> --- Generated on top of v6.2-rc6. .../bindings/display/himax,hx8357d.txt | 2 +- .../bindings/display/ilitek,ili9225.txt | 2 +- .../bindings/display/multi-inno,mi0283qt.txt | 2 +- .../bindings/display/panel/lg,lg4573.yaml | 2 +- .../display/panel/samsung,lms397kf04.yaml | 2 +- .../devicetree/bindings/display/repaper.txt | 2 +- .../bindings/display/sitronix,st7586.txt | 2 +- .../bindings/iio/accel/adi,adis16240.yaml | 2 +- .../bindings/iio/accel/adi,adxl313.yaml | 2 +- .../bindings/iio/accel/adi,adxl345.yaml | 2 +- .../devicetree/bindings/iio/accel/lis302.txt | 2 +- .../bindings/iio/accel/nxp,fxls8962af.yaml | 2 +- .../bindings/iio/adc/microchip,mcp3201.yaml | 2 +- .../bindings/input/touchscreen/ads7846.txt | 2 +- .../devicetree/bindings/leds/leds-lp8860.txt | 2 +- .../bindings/media/renesas,drif.yaml | 2 +- .../memory-controllers/renesas,rpc-if.yaml | 2 +- .../devicetree/bindings/mfd/atmel-flexcom.txt | 2 +- .../bindings/misc/olpc,xo1.75-ec.yaml | 2 +- .../devicetree/bindings/mmc/mmc-spi-slot.yaml | 2 +- .../bindings/net/dsa/vitesse,vsc73xx.txt | 2 +- .../bindings/net/microchip,enc28j60.txt | 2 +- .../devicetree/bindings/net/wiznet,w5x00.txt | 2 +- .../bindings/spi/brcm,spi-bcm-qspi.yaml | 4 ++-- .../bindings/spi/marvell,mmp2-ssp.yaml | 2 +- .../bindings/spi/mxicy,mx25f0a-spi.yaml | 2 +- .../bindings/spi/snps,dw-apb-ssi.yaml | 2 +- .../devicetree/bindings/spi/spi-mux.yaml | 2 +- .../bindings/spi/spi-peripheral-props.yaml | 2 +- Documentation/driver-api/mtd/spi-nor.rst | 4 ++-- .../firmware-guide/acpi/enumeration.rst | 2 +- .../firmware-guide/acpi/gpio-properties.rst | 2 +- .../sound/designs/compress-offload.rst | 2 +- Documentation/spi/spi-lm70llp.rst | 4 ++-- Documentation/spi/spidev.rst | 4 ++-- arch/arm/boot/dts/imx7d-flex-concentrator.dts | 2 +- .../cavium-octeon/executive/cvmx-helper-spi.c | 6 +++--- arch/mips/cavium-octeon/executive/cvmx-spi.c | 16 ++++++++-------- arch/mips/include/asm/octeon/cvmx-helper-spi.h | 4 ++-- arch/mips/include/asm/octeon/cvmx-spi.h | 18 +++++++++--------- arch/mips/include/asm/octeon/cvmx-wqe.h | 2 +- drivers/auxdisplay/lcd2s.c | 2 +- drivers/gpu/drm/solomon/ssd130x-spi.c | 2 +- drivers/gpu/drm/tiny/ili9486.c | 2 +- drivers/input/misc/Kconfig | 4 ++-- drivers/input/rmi4/Kconfig | 2 +- drivers/input/touchscreen/Kconfig | 2 +- drivers/mfd/Kconfig | 2 +- drivers/mfd/ocelot.h | 2 +- drivers/mmc/host/Kconfig | 2 +- drivers/mtd/spi-nor/controllers/Kconfig | 2 +- drivers/mtd/spi-nor/core.c | 14 +++++++------- drivers/mtd/spi-nor/core.h | 4 ++-- drivers/mtd/spi-nor/sfdp.c | 6 +++--- .../net/dsa/sja1105/sja1105_dynamic_config.c | 4 ++-- drivers/net/ethernet/microchip/enc28j60.c | 2 +- .../net/wireless/microchip/wilc1000/Kconfig | 2 +- drivers/net/wireless/st/cw1200/Kconfig | 2 +- drivers/platform/chrome/Kconfig | 2 +- drivers/platform/chrome/cros_ec_spi.c | 2 +- drivers/rtc/rtc-ds1305.c | 2 +- drivers/spi/Kconfig | 8 ++++---- drivers/spi/spi-mem.c | 10 +++++----- drivers/spi/spi-mpc52xx-psc.c | 2 +- drivers/spi/spi.c | 4 ++-- drivers/staging/fbtft/fbtft.h | 2 +- drivers/staging/iio/meter/Kconfig | 2 +- drivers/staging/octeon/ethernet-spi.c | 2 +- drivers/usb/host/max3421-hcd.c | 2 +- include/linux/mtd/spinand.h | 14 +++++++------- include/linux/rmi.h | 2 +- include/linux/spi/spi-mem.h | 18 +++++++++--------- include/linux/spi/spi.h | 8 ++++---- 73 files changed, 131 insertions(+), 131 deletions(-) diff --git a/Documentation/devicetree/bindings/display/himax,hx8357d.txt b/Documentation/devicetree/bindings/display/himax,hx8357d.txt index e641f664763d..ed7aebbd3c69 100644 --- a/Documentation/devicetree/bindings/display/himax,hx8357d.txt +++ b/Documentation/devicetree/bindings/display/himax,hx8357d.txt @@ -8,7 +8,7 @@ Required properties: - dc-gpios: D/C pin - reg: address of the panel on the SPI bus -The node for this driver must be a child node of a SPI controller, hence +The node for this driver must be a child node of an SPI controller, hence all mandatory properties described in ../spi/spi-bus.txt must be specified.

ALSA: emux: Avoid potential array out-of-bound in snd_emux_xg_control()
by Артемий Карасев 03 Feb '23

03 Feb '23

In snd_emux_control() method "snd_emux_port" can be passed with field chset.midi_mode == SNDRV_MIDI_MODE_XG. The "type" can be MIDI_CTL_PITCHBEND or MIDI_CTL_CHAN_PRESSURE. It may lead to accessing 'control' array of size 128 with MIDI_CTL_PITCHBEND (0x80) or MIDI_CTL_CHAN_PRESSURE (0x82) index. How can we prevent this? Would it be a good solution to place code like this before call snd_emux_xg_control()? if (type == MIDI_CTL_PITCHBEND || type == MIDI_CTL_CHAN_PRESSURE){ return; } Found by Linux Verification Center (linuxtesting.org) with SVACE.

[PATCH 00/15] ASoC: rsnd: cleanup add R-Car Gen4 Sound support
by Kuninori Morimoto 03 Feb '23

Hi Mark This patch-set adds R-Car Gen4 support on Renesas sound driver. To add it, it needs some cleanups / prepares which makes easy to review the patch. Kuninori Morimoto (15): ASoC: rsnd: check whether playback/capture property exists ASoC: rsnd: fixup #endif position ASoC: rsnd: Remove unnecessary rsnd_dbg_dai_call() ASoC: rsnd: indicate necessary error when clock start failed ASoC: rsnd: indicate warning once if it can't handle requested rule ASoC: rsnd: use same debug message format on clkout ASoC: rsnd: remove unnecessary ADG flags ASoC: rsnd: rename clk to clkin ASoC: rsnd: moves clkout_name to top of the file ASoC: rsnd: use clkin/out_size ASoC: rsnd: use array for 44.1kHz/48kHz rate handling ASoC: rsnd: tidyup rsnd_dma_addr() ASoC: rsnd: dma.c: tidyup rsnd_dma_probe() ASoC: dt-bindings: renesas: add R8A779G0 V4H ASoC: rsnd: add R-Car Gen4 Sound support .../bindings/sound/renesas,rsnd.yaml | 4 + sound/soc/sh/rcar/adg.c | 169 ++++++++++-------- sound/soc/sh/rcar/core.c | 66 ++++--- sound/soc/sh/rcar/dma.c | 57 +++++- sound/soc/sh/rcar/gen.c | 70 ++++++++ sound/soc/sh/rcar/rsnd.h | 23 ++- sound/soc/sh/rcar/ssi.c | 13 +- sound/soc/sh/rcar/ssiu.c | 15 +- 8 files changed, 289 insertions(+), 128 deletions(-) -- 2.25.1

Is there any way to install alsa-lib with the suid bit set?
by Stefan Alexe 03 Feb '23

03 Feb '23

I am trying to only use a static /dev. I have opened an issue about this on GitHub and got it to work only as the root user. This resembles my experience with xorg. In that case I had to use the suid use flag. Is there an equivalent in this situation?
