Subject: [PATCH] drm: Install pwm modules on all architectures
|
||
|
|
|
||
|
|
At least on x86 on Bay and Cherry Trail devices the pmw-lpss modules must
|
||
|
|
be in the initrd too, otherwise the i915 driver will still load, but
|
||
|
|
it will report the following error:
|
||
|
|
|
||
|
|
[drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm chip
|
||
|
|
|
||
|
|
And not register /sys/class/backlight/intel_backlight and users will
|
||
|
|
not be able to control their backlight.
|
||
|
