ISA AZT2320 driver code contains lots of assignments in if condition, which is a bad coding style that may confuse readers and occasionally lead to bugs.

snd_sb_qsound_destroy() contains the calls of removing the previously created mixer controls, but it doesn't clear the pointers. As snd_sb_qsound_destroy() itself may be repeatedly called via ioctl, this could lead to double-free potentially. Fix it by clearing the struct fields properly afterwards.

The handling of snd_ctl_new1() and snd_ctl_add() can be sometimes tricky, as snd_ctl_add() automatically removes the passed object at its error path. The recent fix addressed an overlooked issue that is relevant with that in SB driver code, and it can be a bit more simplified by assigning to a temporary variable, i.e. storing to the struct field only after the creation succeeds.

A lot of code for SB drivers is in a legacy style with assignment in if condition. This also made harder to catch some bugs (e.g. the commit 1c98f574 "ALSA: emu8000: Fix a use after free in snd_emu8000_create_mixer"). This patch fixes the coding style. All are rather simple conversions and there should be no functional changes. (The changes in snd_emu8000_new() for hw->res_port1, 2 and 3 are slightly different from the older ones, but this shouldn't matter much in practice.)

There are 2 issues on this machine, the 1st one is mic's plug/unplug can't be detected, that is because the mic is set to manual detecting mode, need to apply ALC255_FIXUP_XIAOMI_HEADSET_MIC to set it to auto detecting mode. The other one is headphone's plug/unplug can't be detected by pulseaudio, that is because the pulseaudio will use ucm2/sof-hda-dsp on this machine, and the ucm2 only handle 'Headphone Jack', but on this machine the headphone's pincfg sets the location to Front, then the alsa mixer name is "Front Headphone Jack" instead of "Headphone Jack", so override the pincfg to change location to Left.

In the workqueue to queue wake-up event, isochronous context is not processed, thus it's useless to check context for the workqueue to switch status of runtime for PCM substream to XRUN. On the other hand, in software IRQ context of 1394 OHCI, it's needed. This commit fixes the bug introduced when tasklet was replaced with workqueue.

The patch_realtek.c needs to check if the power_state.event equals PM_EVENT_SUSPEND, after using the direct-complete, the suspend() and resume() will be skipped if the codec is already rt_suspended, in this case, the patch_realtek.c will always get PM_EVENT_ON even the system is really resumed from S3. We could set power_state to PMSG_SUSPEND in the prepare(), if other PM functions are called before complete(), those functions will override power_state; if no other PM functions are called before complete(), we could know the suspend() and resume() are skipped since only S3 pm functions could be skipped by direct-complete, in this case set power_state to PMSG_RESUME in the complete(). This could guarantee the first time of calling hda_codec_runtime_resume() after complete() has the correct power_state.

snd_timer_notify1() calls the notification to each slave for a master event, but it passes a wrong event number. It should be +10 offset, corresponding to SNDRV_TIMER_EVENT_MXXX, but it's incorrectly with +100 offset. Casually this was spotted by UBSAN check via syzkaller.

The snd_ctl_led_sysfs_add and snd_ctl_led_sysfs_remove should contain the refcount operations in pair. However, snd_ctl_led_sysfs_remove fails to decrease the refcount to zero, which causes device_release never to be invoked. This leads to memory leak to some resources, like struct device_private. In addition, we also free some other similar memory leaks in snd_ctl_led_init/snd_ctl_led_exit. Fix this by replacing device_del to device_unregister in snd_ctl_led_sysfs_remove/snd_ctl_led_init/snd_ctl_led_exit. Note that, when CONFIG_DEBUG_KOBJECT_RELEASE is enabled, put_device will call kobject_release and delay the release of kobject, which will cause use-after-free when the memory backing the kobject is freed at once.

USB-audio driver behaves a bit strangely for the playback stream -- namely, it starts sending silent packets at PCM prepare state while the actual data is submitted at first when the trigger START is kicked off. This is a workaround for the behavior where URBs are processed too quickly at the beginning. That is, if we start submitting URBs at trigger START, the first few URBs will be immediately completed, and this would result in the immediate period-elapsed calls right after the start, which may confuse applications. OTOH, submitting the data after silent URBs would, of course, result in a certain delay of the actual data processing, and this is rather more serious problem on modern systems, in practice. This patch tries to revert the workaround and lets the URB submission starting at PCM trigger for the playback again. As far as I've tested with various backends (native ALSA, PA, JACK, PW), I haven't seen any problems (famous last words :) Note that the capture stream handling needs no such workaround, since the capture is driven per received URB.
