[Description] In newer DCN's the programming of SYMCLK_FE_SRC_SEL depends on the value of DIG_FE_SOURCE_SELECT. If DIG_FE_SOURCE_SELECT is not already programmed at the time of PHY / DIG enable then the FW sequence will program an incorrect SYMCLK source. Ensure that we program DIG_FE_SOURCE_SELECT for all DIO scenarios (DVI in this particular case) before going through the PHY / DIG enable sequence. Reviewed-by:

drm/amd/display: Add NULL check for 'afb' before dereferencing in amdgpu_dm_plane_handle_cursor_update This commit adds a null check for the 'afb' variable in the amdgpu_dm_plane_handle_cursor_update function. Previously, 'afb' was assumed to be null, but was used later in the code without a null check. This could potentially lead to a null pointer dereference.

This commit adds null checks for the 'stream' and 'plane' variables in the dcn30_apply_idle_power_optimizations function. These variables were previously assumed to be null at line 922, but they were used later in the code without checking if they were null. This could potentially lead to a null pointer dereference, which would cause a crash. The null checks ensure that 'stream' and 'plane' are not null before they are used, preventing potential crashes.
