[PATCH 6.5] ASoC: cs35l56: Call pm_runtime_dont_use_autosuspend()
by Richard Fitzgerald 03 Oct '23

03 Oct '23

commit ec03804552e9a723569e14d2512f36a8e70dc640 upstream Driver remove() must call pm_runtime_dont_use_autosuspend(). Drivers that call pm_runtime_use_autosuspend() must disable it in driver remove(). Unfortunately until recently this was only mentioned in 1 line in a 900+ line document so most people hadn't noticed this. It has only recently been added to the kerneldoc of pm_runtime_use_autosuspend(). Backport note: This is the same change as the upstream commit but the cs35l56->base.dev argument in the upstream code is cs35l56->dev in older releases.

[PATCH v2 2/2] ASoC: Adds support for TAS575x to the pcm512x driver

[PATCH v5 00/12] sound: Use -EPROBE_DEFER instead of i915 module loading.
by Maarten Lankhorst 02 Oct '23

02 Oct '23

Explicitly loading i915 becomes a problem when upstreaming the new intel driver for Tiger Lake and higher graphics (xe). By loading i915, it doesn't wait for driver load of xe, and will fail completely before it loads. -EPROBE_DEFER has to be returned before any device is created in probe(), otherwise the removal of the device will cause EPROBE_DEFER to try again in an infinite loop. The conversion is done in gradual steps. First I add an argument to snd_hdac_i915_init to allow for -EPROBE_DEFER so I can convert each driver separately. Then I convert each driver to move snd_hdac_i915_init out of the workqueue. Finally I drop the ability to choose modprobe behavior after the last user is converted. Compared to previous version, I added a fix for sof_ops_free() missing call, renamed probe_no_wq and remove_no_wq to probe_early/probe_late, and fixed the resulting fallout.
