ASoC: Fixes for v4.3 Quite a few fixes here but they're all very small and driver specific, none of them really stand out if you aren't using the relevant hardware but they're all useful if you do happen to have an affected device.
The minimum volume level for the TAS2552 (control register value 0x00) is -7dB however the driver declares it as -0.07dB. Running amixer before the patch reports: dBscale-min=-0.07dB,step=1.00dB,mute=0 Running amixer with the patch applied reports: dBscale-min=-7.00dB,step=1.00dB,mute=0 Signed-off-by: Andreas Dannenberg <dannenberg@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
When OSS emulation is loaded on ISA SB AWE32 chip, we get now kernel warnings like: WARNING: CPU: 0 PID: 2791 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x51/0x80() sysfs: cannot create duplicate filename '/devices/isa/sbawe.0/sound/card0/seq-oss-0-0' It's because both emux synth and opl3 drivers try to register their OSS device object with the same static index number 0. This hasn't been a big problem until the recent rewrite of device management code (that exposes sysfs at the same time), but it's been an obvious bug. This patch works around it just by using a different index number of emux synth object. There can be a more elegant way to fix, but it's enough for now, as this code won't be touched so often, in anyway.

The recent widget power saving introduced some unavoidable click noises on old IDT 92HD73xx chips while it still seems working on the compatible new chips. In the bugzilla, we tried lots of tests and workarounds, but they didn't help much. So, let's disable the feature for these specific chips as the least (but safest) fix.

The MacBookPro 12,1 has the same setup as the 11 for controlling the status of the optical audio light. Simply apply the existing workaround to the subsystem ID for the 12,1.

Designware I2S uses tx empty and rx available signals as the DMA handshaking signals. during music playing, if XRUN occurs, i2s_stop() function will be executed and both tx and rx irq are masked, when music continues to be played, i2s_start() is executed but both tx and rx irq are not unmasked which cause I2S stop sending DMA handshaking signal to DMA controller, and it finally causes music playing will be stopped once XRUN occurs for the first time.

from Designware I2S datasheet, tx/rx XRUN irq is cleared by reading register TOR/ROR, rather than by writing into them. Signed-off-by: Yitian Bu <yitian.bu@tangramtek.com> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
