Subject: drm/amdgpu: Replace ternary operator with min() in 'amdgpu_iomem_read'
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=44fd83e920e2ec0322ad82320ca575445b5e135e;p=linux.git

drm/amdgpu: Replace ternary operator with min() in 'amdgpu_iomem_read'

Fixes the following coccicheck:

drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:2427:16-17: WARNING opportunity for min()

min() macro is defined in include/linux/minmax.h. It avoids multiple
evaluations of the arguments when non-constant and performs strict
type-checking.
