ASoC: tlv320aic32x4: Kernel OOPS while entering DAPM standby mode

2019-01-31T07:15:36+00:00

commit 667e9334fa64da2273e36ce131b05ac9e47c5769 upstream. During the bootup of the kernel, the DAPM bias level is in the OFF state. As soon as the DAPM framework kicks in it pushes the codec into STANDBY state. The probe function doesn't prepare the clock, and STANDBY state does a clk_disable_unprepare() without checking the previous state. This leads to an OOPS. Not transitioning from an OFF state to the STANDBY state fixes the problem. Signed-off-by: b-ak Signed-off-by: Mark Brown Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman

ASoC: rt5514-spi: Fix potential NULL pointer dereference

commit 060d0bf491874daece47053c4e1fb0489eb867d2 upstream. There is a potential NULL pointer dereference in case devm_kzalloc() fails and returns NULL. Fix this by adding a NULL check on rt5514_dsp.

ASoC: wm97xx: fix uninitialized regmap pointer problem

2019-01-26T08:20:39+00:00

[ Upstream commit 576ce4075bfa0f03e0e91a89eecc539b3b828b08 ] gcc notices that without either the ac97 bus or the pdata, we never initialize the regmap pointer, which leads to an uninitialized variable access: sound/soc/codecs/wm9712.c: In function 'wm9712_soc_probe': sound/soc/codecs/wm9712.c:666:2: error: 'regmap' may be used uninitialized in this function [-Werror=maybe-uninitialized] Since that configuration is invalid, it's better to return an error here. I tried to avoid adding complexity to the conditions, and turned the #ifdef into a regular if(IS_ENABLED()) check for readability. This in turn requires moving some header file declarations out of an #ifdef. The same code is used in three drivers, all of which I'm changing the same way.

Merge tag 'asoc-v4.20-rc4' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2018-11-27T15:06:42+00:00

ASoC: Fixes for v4.20 Lots of fixes here, the majority of which are driver specific but there's a couple of core things and one notable driver specific one: - A core fix for a DAPM regression introduced during the component refactoring, we'd lost the code that forced a reevaluation of the DAPM graph after probe (which we suppress during init to save lots of recalcuation) and have now restored it. - A core fix for error handling using the newly added for_each_rtd_codec_dai_rollback() macro. - A fix for the names of widgets in the newly introduced pcm3060 driver, merged as a fix so we don't have a release with legacy names.

ASoC: pcm186x: Fix device reset-registers trigger value

2018-11-15T19:23:48+00:00

According to the current device datasheet (TI Lit # SLAS831D, revised March 2018) the value written to the device's PAGE register to trigger a complete register reset should be 0xfe, not 0xff. So go ahead and update to the correct value. Reported-by: Stephane Le Provost Tested-by: Stephane Le Provost Signed-off-by: Andreas Dannenberg Acked-by: Andrew F.
