2017-12-05UPSTREAM: ASoC: es8328: Remove some unused definesLars-Peter Clausen
The es8328 drivers seems to have used the wm8753 driver as a template. Its header file contains a few defines that are copied verbatim from the wm8753 header that do not really apply to this driver and are unused. So remove those defines. This seems safe as they deal with PLL and clock divider settings and the es8328 driver neither implements a set_pll() nor a set_clkdiv() callback.

2017-12-05UPSTREAM: ASoC: es8328: Enabling support for 192kRomain Perier
The master and slave modes don't share the same table for MCLK/LRCLK ratios. The slaves mode has bigger ratios that allow to use BCLK that matche sampling frequency of 192khz. This commit enables this rate only for slave mode, i.e it does not declare this frequency in sysclk_contraints, resulting to an error in master mode (not supported CLK).

2017-12-05UPSTREAM: ASoC: es8328: Let device auto detect ratios in slave modeRomain Perier
In master mode, SCLK and LRCLK signals are generated by the CODEC when any of the ADC/DAC are enabled. SCLK is derived from MCLK via a programmable division set by BLK_DIV, LRCLK is derived from MCLK via another programmable division set by ADCFsRatio/DACFsRatio. In slave mode, SCLK and LRCLK signals are received as inputs and supplied externally. LRCLK and SCLK must be synchronously derived from MCLK with specific rates. The device can auto detect MCLK/LRCLK ratio according to a predefined table. LRCLK/SCLK ratio is usually 64 (SCLK = 64 * LRCLK) This commits adds support to let to device auto detect and decide which ratio to use. The mclkdiv2 and BCLK_DIV ratio and put to zero.

commit 3d4e8303f2c747c8540a0a0126d0151514f6468b upstream. Some timer compat ioctls have NULL checks of timer instance with snd_BUG_ON() that bring up WARN_ON() when the debug option is set. Actually the condition can be met in the normal situation and it's confusing and bad to spew kernel warnings with stack trace there. Let's remove snd_BUG_ON() invocation and replace with the simple checks. Also, correct the error code to EBADFD to follow the native ioctl error handling.

2017-11-30ALSA: pcm: update tstamp only if audio_tstamp changedHenrik Eriksson
commit 20e3f985bb875fea4f86b04eba4b6cc29bfd6b71 upstream. commit 3179f6200188 ("ALSA: core: add .get_time_info") had a side effect of changing the behaviour of the PCM runtime tstamp. Prior to this change tstamp was not updated by snd_pcm_update_hw_ptr0() unless the hw_ptr had moved, after this change tstamp was always updated. For an application using alsa-lib, doing snd_pcm_readi() followed by snd_pcm_status() to estimate the age of the read samples by subtracting status->avail * [sample rate] from status->tstamp this change degraded the accuracy of the estimate on devices where the pcm hw does not provide a granular hw_ptr, e.g., devices using soc-generic-dmaengine-pcm.c and a dma-engine with residue_granularity DMA_RESIDUE_GRANULARITY_DESCRIPTOR. The accuracy of the estimate depended on the latency between the PCM hw completing a period and the driver called snd_pcm_period_elapsed() to notify ALSA core, typically determined by interrupt handling latency. After the change the accuracy of the estimate depended on the latency between the PCM hw completing a period and the application calling snd_pcm_status(), determined by the scheduling of the application process. The maximum error of the estimate is one period length in both cases, but the error average and variance is smaller when it depends on interrupt latency. Instead of always updating tstamp, update it only if audio_tstamp changed.

2017-11-15ALSA: seq: Fix OSS sysex delivery in OSS emulationTakashi Iwai
commit 132d358b183ac6ad8b3fea32ad5e0663456d18d1 upstream. The SYSEX event delivery in OSS sequencer emulation assumed that the event is encoded in the variable-length data with the straight buffering. This was the normal behavior in the past, but during the development, the chained buffers were introduced for carrying more data, while the OSS code was left intact. As a result, when a SYSEX event with the chained buffer data is passed to OSS sequencer port, it may end up with the wrong memory access, as if it were having a too large buffer. This patch addresses the bug, by applying the buffer data expansion by the generic snd_seq_dump_var_event() helper function.

2017-11-14UPSTREAM: ALSA: timer: Call notifier in the same spinlockTakashi Iwai
snd_timer_notify1() is called outside the spinlock and it retakes the lock after the unlock. This is rather racy, and it's safer to move snd_timer_notify() call inside the main spinlock. The patch also contains a slight refactoring / cleanup of the code. Now all start/stop/continue/pause look more symmetric and a bit better readable.

2017-11-08ASoC: adau17x1: Workaround for noise bug in ADCRicard Wanderlof
commit 1e6f4fc06f6411adf98bbbe7fcd79442cd2b2a75 upstream. The ADC in the ADAU1361 (and possibly other Analog Devices codecs) exhibits a cyclic variation in the noise floor (in our test setup between -87 and -93 dB), a new value being attained within this range whenever a new capture stream is started. The cycle repeats after about 10 or 11 restarts. The workaround recommended by the manufacturer is to toggle the ADOSR bit in the Converter Control 0 register each time a new capture stream is started. I have verified that the patch fixes this problem on the ADAU1361, and according to the manufacturer toggling the bit in question in this manner will at least have no detrimental effect on other chips served by this driver.

2017-11-08ALSA: seq: Fix nested rwsem annotation for lockdep splatTakashi Iwai
commit 1f20f9ff57ca23b9f5502fca85ce3977e8496cb1 upstream. syzkaller reported the lockdep splat due to the possible deadlock of grp->list_mutex of each sequencer client object. Actually this is rather a false-positive report due to the missing nested lock annotations. The sequencer client may deliver the event directly to another client which takes another own lock. For addressing this issue, this patch replaces the simple down_read() with down_read_nested(). As a lock subclass, the already existing "hop" can be re-used, which indicates the depth of the call.

2017-11-08ALSA: timer: Add missing mutex lock for compat ioctlsTakashi Iwai
commit 79fb0518fec8c8b4ea7f1729f54f293724b3dbb0 upstream. The races among ioctl and other operations were protected by the commit af368027a49a ("ALSA: timer: Fix race among timer ioctls") and later fixes, but one code path was forgotten in the scenario: the 32bit compat ioctl. As syzkaller recently spotted, a very similar use-after-free may happen with the combination of compat ioctls. The fix is simply to apply the same ioctl_lock to the compat_ioctl callback, too.
