[PATCH] ASoC: fsl: lpc3xxx-i2s: Include bitfield.h for FIELD_PREP
by Nathan Chancellor 02 Jul '24

bitfield.h is not explicitly included but it is required for FIELD_PREP to be expanded by the preprocessor. If it is not implicitly included, there will be a compiler error (as seen with ARCH=hexagon allmodconfig): sound/soc/fsl/lpc3xxx-i2s.c:169:10: error: call to undeclared function 'FIELD_PREP'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 169 | tmp |= LPC3XXX_I2S_WW8 | LPC3XXX_I2S_WS_HP(LPC3XXX_I2S_WW8_HP); | ^ sound/soc/fsl/lpc3xxx-i2s.h:42:30: note: expanded from macro 'LPC3XXX_I2S_WW8' 42 | #define LPC3XXX_I2S_WW8 FIELD_PREP(0x3, 0) /* Word width is 8bit */ | ^ sound/soc/fsl/lpc3xxx-i2s.c:205:34: error: call to undeclared function 'FIELD_PREP'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 205 | LPC3XXX_I2S_DMA1_TX_EN | LPC3XXX_I2S_DMA0_TX_DEPTH(4)); | ^ sound/soc/fsl/lpc3xxx-i2s.h:65:38: note: expanded from macro 'LPC3XXX_I2S_DMA0_TX_DEPTH' 65 | #define LPC3XXX_I2S_DMA0_TX_DEPTH(s) FIELD_PREP(0xF0000, s) /* Set the DMA1 TX Request level */ | ^ sound/soc/fsl/lpc3xxx-i2s.c:210:34: error: call to undeclared function 'FIELD_PREP'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] 210 | LPC3XXX_I2S_DMA0_RX_EN | LPC3XXX_I2S_DMA1_RX_DEPTH(4)); | ^ sound/soc/fsl/lpc3xxx-i2s.h:70:38: note: expanded from macro 'LPC3XXX_I2S_DMA1_RX_DEPTH' 70 | #define LPC3XXX_I2S_DMA1_RX_DEPTH(s) FIELD_PREP(0x700, s) /* Set the DMA1 RX Request level */ | ^ Include bitfield.h explicitly, so that FIELD_PREP is always expanded, clearing up the compiler error.

[PATCH 1/2] ASoC: codecs: lpass-rx-macro: Fix using NULL pointer in probe() dev_err
by Krzysztof Kozlowski 02 Jul '24

02 Jul '24

The 'rx->dev' is assigned closer to the end of the probe() function, so the dev_err() must not use it - it is still NULL at this point. Instead there is already a local 'dev' variable.

[PATCH] drivers:soundwire: qcom: cleanup port maask calculations
by Srinivas Kandagatla 02 Jul '24

Cleanup the port map calculations, existing masks of having separate masks for in and out ports is not really required.

[PATCH] ASoC: fsl: lpc3xxx-i2s: Avoid using ret uninitialized in lpc32xx_i2s_probe()
by Nathan Chancellor 01 Jul '24

01 Jul '24

clang points out that ret may be used uninitialized in lpc32xx_i2s_probe() in an error pointer path (which becomes fatal with CONFIG_WERROR): sound/soc/fsl/lpc3xxx-i2s.c:326:47: error: variable 'ret' is uninitialized when used here [-Werror,-Wuninitialized] 326 | "failed to init register map: %d\n", ret); | ^~~ sound/soc/fsl/lpc3xxx-i2s.c:310:9: note: initialize the variable 'ret' to silence this warning 310 | int ret; | ^ | = 0 1 error generated. One solution would be a small refactoring of the second parameter in dev_err_probe(), PTR_ERR(i2s_info_p->regs), to be the value of ret in the if statement. However, a nicer solution for debugging purposes, which is the point of this statement, would be to use the '%pe' specifier to symbolically print the error pointer value. Do so, which eliminates the uninitialized use of ret, clearing up the warning.

ucm2/conf.d: add symlink for Qualcomm DB820c
by GitHub pull_request - opened 01 Jul '24

01 Jul '24

alsa-project/alsa-ucm-conf pull request #428 was opened from lumag: Since the release 6.3 Linux kernel uses driver name apq8096 for Qualcomm Dragonboard 820c. This makes alsaucm look for conf.d/apq8096/DB820c.conf and then for conf.d/apq8096/apq8096.conf, while alsa-ucm-conf has historical conf.d/DB820c/DB820c.conf symlink. Add symlink to provide correct configuration for the device.

[PATCH 0/3] ALSA: update sample rate definition for eARC
by Jerome Brunet 01 Jul '24

01 Jul '24

This patchset updates some sample rate definition for eARC support. Notably it: * adds the definition for 128kHz * update the ASoC spdif codecs to include all supported rates, up to 768kHz * adds missing IEC958 definition for 128k, 352.4k, 384k and 705.6kHz On that last point, as noted in the related commit description, I'd like to stress that I have found the definitions using a testing equipement. I do not have access to the IEC958 specification. It would be best if someone with access to this specification could review/ack patch #2, before applying it.
