From: Chris Wilson Date: Fri, 24 Jun 2016 13:00:13 +0000 (+0100) Subject: drm/i915: Move panel's backlight setup next to panel init X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fda9ee98230cd4799cddaede37ab3051ac7645df;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: Move panel's backlight setup next to panel init Currently setting up the backlight for a panel is sometimes done together with initialising the panel, and sometimes after the connector is registered. The backlight setup does not depend upon connector registration (i.e. access to sysfs/debugfs and the kobject hierachy) so perform it consistently just after panel initialisation. Note the discrepancy here as destroying the panel is done during connector unregistration...
