2017-10-25locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns ↵Gravatar Mark Rutland 1-3/+3
to READ_ONCE()/WRITE_ONCE() Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Paul E.

2015-07-29ASoC: xtfpga-i2s: Add missing __rcu annotationGravatar Lars-Peter Clausen 1-1/+1
tx_substeam is accessed using the RCU API and hence should have the __rcu annotation. Fixes the following sparse warnings: sound/soc/xtensa/xtfpga-i2s.c:165:24: error: incompatible types in comparison expression (different address spaces) sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream [noderef] <asn:4>*' versus sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream *' sound/soc/xtensa/xtfpga-i2s.c:255:24: error: incompatible types in comparison expression (different address spaces) sound/soc/xtensa/xtfpga-i2s.c:255:24: error: 'struct snd_pcm_substream [noderef] <asn:4>*' versus sound/soc/xtensa/xtfpga-i2s.c:255:24: error: 'struct snd_pcm_substream *' Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-07-23ASoC: xtensa: Remove unnecessary snd_pcm_lib_preallocate_free_for_all()Gravatar Vaishali Thakkar 1-6/+0
The ALSA core takes care that all preallocated memory is freed when the PCM itself is freed. There is no need to do this manually in the driver. Signed-off-by: Vaishali Thakkar <vthakkar1994@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-01-08ASoC: add xtensa xtfpga I2S interface and platformGravatar Max Filippov 3-0/+685
XTFPGA boards provides an audio subsystem that consists of TI CDCE706 clock synthesizer, I2S transmitter and TLV320AIC23 audio codec. I2S transmitter has MMIO-based interface that resembles that of the OpenCores I2S transmitter. I2S transmitter is always a master on I2S bus. There's no specialized audio DMA, sample data are transferred to I2S transmitter FIFO by CPU through memory-mapped queue interface.
