This avoids bringing back the problem introduced by 62ba568f ("ALSA: pcm: Return 0 when size < start_threshold in capture") and fixed in 00a399ca ("ALSA: pcm: Revert capture stream behavior change in blocking mode"), which prevented the user from starting capture from another thread. Signed-off-by:

BE dai links only have internal PCM's and their substream ops may not be set. Suspending these PCM's will result in their ops->trigger() being invoked and cause a kernel oops. So skip suspending PCM's if their ops are NULL. [ NOTE: this change is required now for following the recent PCM core change to get rid of snd_pcm_suspend() call. Since DPCM BE takes the runtime carried from FE while keeping NULL ops, it can hit this bug.

In the commit 62ba568f ("ALSA: pcm: Return 0 when size < start_threshold in capture"), we changed the behavior of __snd_pcm_lib_xfer() to return immediately with 0 when a capture stream has a high start_threshold. This was intended to be a correction of the behavior consistency and looked harmless, but this was the culprit of the recent breakage reported by syzkaller, which was fixed by the commit e190161f ("ALSA: pcm: Fix tight loop of OSS capture stream"). At the time for the OSS fix, I didn't touch the behavior for ALSA native API, as assuming that this behavior actually is good. But this turned out to be also broken actually for a similar deployment, e.g. one thread goes to a write loop in blocking mode while another thread controls the start/stop of the stream manually. Overall, the original commit is harmful, and it brings less merit to keep that behavior. Let's revert it.

Now all callers no longer check the return value from snd_pcm_lib_preallocate_pages() and co, let's make them to return void, so that any new code won't fall into the same pitfall. Reviewed-by:

Merge tag 'asoc-v5.1' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v5.1 Lots and lots of new drivers so far, a highlight being the MediaTek BTCVSD which is a driver for a Bluetooth radio chip - the first such driver we've had upstream. Hopefully we will soon also see a baseband with an upstream driver! - Support for only powering up channels that are actively being used. - Quite a few improvements to simplify the generic card drivers, especially the merge of the SCU cards into the main generic drivers. - Lots of fixes for probing on Intel systems, trying to rationalize things to look more standard from a framework point of view. - New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341, Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.

The commit a60945fd ("ALSA: usb-audio: move implicit fb quirks to separate function") introduced an error in the handling of quirks for implicit feedback endpoints. This commit fixes this. If a quirk successfully sets up an implicit feedback endpoint, usb-audio no longer tries to find the implicit fb endpoint itself.
