Subject: [PATCH 1262/1350] drm: panel: ili9881: Correct symmetry on
|
||
|
enable/disable return codes
|
||
|
|
||
|
ili9881c_enable is always returning 0.
|
||
|
|
||
|
ili9881c_disable was returning the error code from
|
||
|
mipi_dsi_dcs_set_display_off.
|
||
|
If non-zero, the drm_panel framework will leave the panel marked as
|
||
|
enabled, and not run the enable hook next time around. That isn't
|
||
|
helpful, particularly as we're expecting unprepare to disable
|
||
|
resets and regulators.
|
||
|
|
||
|
Change ili9881c_disable to match enable in always returning 0.
