We apply the codec resume forcibly at system resume callback for updating and syncing the jack detection state that may have changed during sleeping. This is, however, superfluous for the codec like Intel HDMI/DP, where the jack detection is managed via the audio component notification; i.e. the jack state change shall be reported sooner or later from the graphics side at mode change. This patch changes the codec resume callback to avoid the forcible resume conditionally with a new flag, codec->relaxed_resume, for reducing the resume time. The flag is set in the codec probe. Although this doesn't fix the entire bug mentioned in the bugzilla entry below, it's still a good optimization and some improvements are seen.

The recent fix for Icelake HDMI codec introduced the mapping from pin NID to the i915 gfx port number. However, it forgot the reverse mapping from the port number to the pin NID that is used in the ELD notifier callback. As a result, it's processed to a wrong widget and gives a warning like snd_hda_codec_hdmi hdaudioC0D2: HDMI: pin nid 5 not registered This patch corrects it with a proper reverse mapping function.

The fix for the racy writes and ioctls to sequencer widened the application of client->ioctl_mutex to the whole write loop. Although it does unlock/relock for the lengthy operation like the event dup, the loop keeps the ioctl_mutex for the whole time in other situations. This may take quite long time if the user-space would give a huge buffer, and this is a likely cause of some weird behavior spotted by syzcaller fuzzer. This patch puts a simple workaround, just adding a mutex break in the loop when a large number of events have been processed. This shouldn't hit any performance drop because the threshold is set high enough for usual operations.

ALSA: firewire-lib: fix initial value of data block count for IR context without CIP_DBC_IS_END_EVENT For IR context, ALSA IEC 61883-1/6 engine uses initial value of data block counter as UINT_MAX, to detect first isochronous packet in the middle of packet streaming. At present, when CIP_DBC_IS_END_EVENT is not used (i.e. for drivers except for ALSA fireworks driver), the initial value is used as is for tracepoints event. However, the engine can detect the value of dbc field in the payload of first isochronous packet and the value should be assigned to the event. This commit fixes the bug.

firewire-motu: fix wrong reference count for stream functionality at error path of rawmidi interface In IEC 61883-6, several types of sampling data can be multiplexed into payload of common isochronous packet (CIP). For typical audio and music units, PCM samples and MIDI messages are multiplexed into one packet streaming. ALSA firewire-motu driver allows applications of rawmidi interface to start packet streaming for transmission of MIDI messages. However at error path, the reference count of stream functionality is not operated correctly. This can brings a bug that packet streaming is not stopped when all referrers release the count.

Along with the recent fix for the races of snd_hdac_refresh_widgets() it turned out that the instantiation of widgets sysfs at snd_hdac_sysfs_reinit() could cause a race. The race itself was already covered later by extending the mutex protection range, the commit 98482377 ("ALSA: hda: Fix widget_mutex incomplete protection"), but this also indicated that the call of *_reinit() is basically superfluous, as the widgets shall be created sooner or later from snd_hdac_device_register(). This patch removes the redundant call of snd_hdac_sysfs_reinit() at first. By this removal, the sysfs argument itself in snd_hdac_refresh_widgets() becomes superfluous, too, because the only case sysfs=false is always with codec->widgets=NULL. So, we drop this redundant argument as well. Signed-off-by:
