[alsa-devel] [RFT 1/2] ASoC: samsung: Fix possible double iounmap on s3c24xx driver probe failure
by Krzysztof Kozlowski 28 Jul '17

28 Jul '17

Commit 87b132bc0315 ("ASoC: samsung: s3c24{xx,12}-i2s: port to use generic dmaengine API") moved ioremap() call from s3c-i2s-v2.c:s3c_i2sv2_probe() to s3c2412-i2s.c:s3c2412_iis_dev_probe() and converted it to devm- resource managed interface. However the error path in first of them - s3c_i2sv2_probe() - was not updated. If getting a iis clock in s3c_i2sv2_probe() failed, the address space would be unmapped there. This could lead to: 1. double iounmap() later from devm-interface of s3c2412_iis_dev_probe()), 2. accessing the memory by other functions in s3c2412-i2s.c unit. Anyway, the owner of this mapped region should be s3c2412-i2s.c because it starts the mapping. Affected are drivers for S3C24xx family although issue was not reproduced. Fixes: 87b132bc0315 ("ASoC: samsung: s3c24{xx,12}-i2s: port to use generic dmaengine API") Signed-off-by: Krzysztof Kozlowski <krzk(a)kernel.org> --- Not marking as Cc-stable because this is theoretical problem, not reproduced and also not tested.

[alsa-devel] [PATCH v1 0/3] add jack detection to MSM8916 analog
by Damien Riegel 27 Jul '17

27 Jul '17

This series adds support for the MBHC (Multi-Button Headset Control) of the PM8916's analog codec. This IP is capable to identify up to five buttons on a headset, but for now only the jack detection is supported. A complete implementation exists in the Android kernel, but it's quite complex and I'd rather go step by step. First patch fixes a define that is squatting a bit used by the MBHC. Second patch is the actual implementation of the jack detection, and third patch plugs the jack detection in the sound card driver.
