2023-03-22drm/amd/display/amdgpu_dm: Refactor register_backlight_device()Hans de Goede1-13/+15
Refactor register_backlight_device(): 1) Turn the connector-type + signal check into an early exit condition to avoid the indentation level of the rest of the code 2) Add an array bounds check for the arrays indexed by dm->num_of_edps 3) register_backlight_device() always increases dm->num_of_edps if amdgpu_dm_register_backlight_device() has assigned a backlight_dev to the current dm->backlight_link[dm->num_of_edps] slot. So on its next call dm->backlight_dev[dm->num_of_edps] always point to the next empty slot and the "if (!dm->backlight_dev[dm->num_of_edps])" check will thus always succeed and can be removed. 4) Add a bl_idx local variable to use as array index, rather then using dm->num_of_edps to improve the code readability.

[Why] The log "DMUB HPD callback" is crucial to identify when DP tunneling is been established and driver is notified of this event from DMUB. Same log is shared for long and short hotplug event and we need to check trailing DC debug log to distinguish between them two, making debugging on DPIA related issues a bit more troublesome.
