Hi,
This is the sixth version of my series, the fourth as a proper
patchset.
These are the changes:
In v4:
* removed the call to init from the first patch (gets added later);
* added a flag to check if the wakelock is taken in DMC, so we
don't try to take it again if get() is called while the work is
queued;
* changed the copyright year to 2024;
* added __intel_dmc_wl_supported() to make checks easier;
* check if supported also on init;
* check if DMC is loaded before enabling;
* removed a couple of stray debugging messages.
In v3:
* Fixed some checkpatch issues.
In v2:
* Enable/disable the wakelocks on DC5-6 entry and exit instead of on
DMC load and unload;
* Added bspec link to the commit message;
* A bunch of other small changes;
* For the complete list of changes and discussions, please look at
the patchset in patchwork:
https://patchwork.freedesktop.org/series/128628/
Please review.
Cheers,
Luca.
