[PATCH v1 1/1] treewide: Align match_string() with sysfs_match_string()
by Andy Shevchenko 10 Jun '24

10 Jun '24

Make two APIs look similar. Hence convert match_string() to be a 2-argument macro. In order to avoid unneeded churn, convert all users as well. There is no functional change intended. Signed-off-by: Andy Shevchenko <andriy.shevchenko(a)linux.intel.com> --- Compile tested with `make allyesconfig` and `make allmodconfig` on x86_64, arm, aarch64, powerpc64 (8 builds total). I guess the best is to apply it to Linus' tree directly. And now it seems a good timing as there are no new users of this API either in v6.10-rcX, or in Linux Next. But if you think differently, tell me. arch/powerpc/xmon/xmon.c | 5 ++-- arch/x86/kernel/cpu/mtrr/if.c | 4 +-- crypto/asymmetric_keys/pkcs7_verify.c | 4 +-- drivers/acpi/scan.c | 4 +-- drivers/ata/pata_hpt366.c | 2 +- drivers/ata/pata_hpt37x.c | 2 +- drivers/base/property.c | 6 ++-- drivers/char/ipmi/ipmi_msghandler.c | 2 +- drivers/char/ipmi/ipmi_si_hardcode.c | 2 +- drivers/clk/bcm/clk-bcm2835.c | 4 +-- drivers/clk/rockchip/clk.c | 4 +-- drivers/clk/tegra/clk-tegra124-emc.c | 7 ++--- drivers/cpufreq/amd-pstate.c | 4 +-- drivers/cpufreq/intel_pstate.c | 2 +- .../intel/qat/qat_common/adf_cfg_services.c | 5 ++-- .../gpu/drm/drm_panel_orientation_quirks.c | 2 +- drivers/gpu/drm/i915/display/intel_pipe_crc.c | 2 +- drivers/gpu/drm/nouveau/dispnv04/tvnv17.c | 4 +-- drivers/gpu/drm/nouveau/dispnv50/crc.c | 2 +- drivers/hwmon/ltc4282.c | 14 ++++----- drivers/hwmon/nct6775-platform.c | 6 ++-- drivers/hwtracing/intel_th/msu.c | 2 +- drivers/i2c/busses/i2c-i801.c | 4 +-- drivers/leds/leds-sun50i-a100.c | 2 +- drivers/mfd/omap-usb-host.c | 2 +- drivers/mmc/host/sdhci-xenon-phy.c | 13 ++++----- drivers/mtd/nand/raw/nand_macronix.c | 10 ++----- .../net/ethernet/chelsio/cxgb4/cudbg_lib.c | 6 ++-- .../net/wireless/intel/iwlwifi/mvm/debugfs.c | 2 +- drivers/pci/pcie/aer.c | 2 +- drivers/phy/mediatek/phy-mtk-tphy.c | 8 ++--- drivers/phy/tegra/xusb.c | 4 +-- drivers/pinctrl/mvebu/pinctrl-armada-37xx.c | 6 ++-- drivers/pinctrl/pinmux.c | 6 ++-- drivers/platform/x86/hp/hp-wmi.c | 29 +++++++------------ drivers/platform/x86/msi-ec.c | 4 +-- drivers/power/supply/ab8500_btemp.c | 2 +- drivers/power/supply/ab8500_chargalg.c | 2 +- drivers/power/supply/ab8500_charger.c | 2 +- drivers/power/supply/ab8500_fg.c | 2 +- drivers/staging/gdm724x/gdm_tty.c | 5 ++-- .../int340x_thermal/processor_thermal_rfim.c | 4 +-- .../processor_thermal_wt_req.c | 2 +- drivers/usb/common/common.c | 8 ++--- drivers/usb/dwc3/dwc3-rtk.c | 2 +- drivers/usb/typec/class.c | 14 ++++----- drivers/usb/typec/tipd/core.c | 3 +- drivers/video/fbdev/pxafb.c | 4 +-- fs/bcachefs/compress.c | 2 +- fs/bcachefs/opts.c | 4 +-- fs/bcachefs/util.c | 4 +-- fs/ubifs/auth.c | 8 ++--- include/linux/string.h | 12 +++++++- kernel/cgroup/rdma.c | 2 +- kernel/sched/debug.c | 2 +- kernel/trace/trace.c | 4 +-- kernel/trace/trace_osnoise.c | 4 +-- lib/dynamic_debug.c | 5 ++-- lib/string_helpers.c | 6 ++-- mm/mempolicy.c | 4 +-- mm/vmpressure.c | 4 +-- security/apparmor/lsm.c | 9 +++--- security/integrity/ima/ima_main.c | 2 +- security/integrity/ima/ima_policy.c | 2 +- sound/firewire/oxfw/oxfw.c | 2 +- sound/pci/oxygen/oxygen_mixer.c | 2 +- sound/soc/codecs/max98088.c | 2 +- sound/soc/codecs/max98095.c | 2 +- sound/soc/soc-dapm.c | 5 ++-- 69 files changed, 150 insertions(+), 174 deletions(-) diff --git a/arch/powerpc/xmon/xmon.c b/arch/powerpc/xmon/xmon.c index bd4813bad317..f479cc62674a 100644 --- a/arch/powerpc/xmon/xmon.c +++ b/arch/powerpc/xmon/xmon.c @@ -3478,8 +3478,7 @@ skipbl(void) return c;

alsa-project/alsa-lib issue #400 was opened from sylware: To have the less "technical distance" with modern audio hardware (for instance usb audio 2), is it better to have interleaved audio frames each with a pitch, or brutally planar with a pitch per plane?

[PATCH v2 0/2] tlv320adc3xxx: Allow MICBIAS pins to be used as GPOs
by Ricard Wanderlof 07 Jun '24

07 Jun '24

In some cases, depending on system design, the MICBIAS pins on the chip are not needed as such, but a couple of extra GPIO pins would be useful. This patch allows the MICBIAS pins to be configured in the device tree as general purpose output pins, controlled via the GPIO framework. Owing to their originally intended purpose there are some limitations: when the MICBIAS pins are deactivated, they will float, so will likely need a pulldown in many applications. When activated, they will assume the voltage specified by the micbias1-vg and micbias2-vg properties, respectively, meaning that the resulting output voltage will be 2.0 V, 2.5 V or AVDD . Signed-off-by: Ricard Wanderlof <ricard.wanderlof(a)axis.com> --- Changes in v2: - Corrected typo in yaml document for ti,micbias2-vg property reference - Added dependecies to yaml document for ti,micbias1-gio and ti,micbias2-gpo - Link to v1: https://lore.kernel.org/r/20240529-tlv320adc3xxx-micbias-gpo-v1-0-300d39cec… --- Ricard Wanderlof (2): ASoC: dt-bindings: tlv320adc3xxx: Add MICBIAS-as-GPO properties tlv320adc3xxx: Add support for using MICBIAS pins as GPO .../bindings/sound/ti,tlv320adc3xxx.yaml | 24 +++++ sound/soc/codecs/tlv320adc3xxx.c | 105 ++++++++++++++++----- 2 files changed, 108 insertions(+), 21 deletions(-) --- base-commit: 47d09270d7776e46858a161f94b735640b2fb056 change-id: 20240528-tlv320adc3xxx-micbias-gpo-b8b4d1c846d3 Best regards, -- -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30
