2024-02-14drm/amdgpu/display: Initialize gamma correction mode variable in ↵Srinivasan Shanmugam1-4/+1
dcn30_get_gamcor_current() The dcn30_get_gamcor_current() function is responsible for determining the current gamma correction mode used by the display controller. However, the 'mode' variable, which stores the gamma correction mode, was not initialized before its first usage, leading to an uninitialized symbol error. Thus initializes the 'mode' variable with a default value of LUT_BYPASS before the conditional statements in the function, improves code clarity and stability, ensuring correct behavior of the dcn30_get_gamcor_current() function in determining the gamma correction mode. Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_dpp_cm.c:77 dpp30_get_gamcor_current() error: uninitialized symbol 'mode'.
