Subject[PATCH] drm/amdgpu/display: make a const array common_rates static, makes object smaller
Date
From: Colin Ian King <colin.king@canonical.com>

Don't populate the const array common_rates on the stack but instead it
static. Makes the object code smaller by 80 bytes:

Before:
text data bss dec hex filename
268019 98322 256 366597 59805 ../display/amdgpu_dm/amdgpu_dm.o

After:
text data bss dec hex filename
267843 98418 256 366517 597b5 ../display/amdgpu_dm/amdgpu_dm.o

Reduction of 80 bytes

(gcc version 10.3.0)
