Subject: [PATCH -next] drm/i915: Fix some integer constant macro to unsigned type
Build Kernel with gcc 7.5.0 or older, will get some error message:
drivers/gpu/drm/i915/display/intel_ddi.c:1915:2: error: case label does not reduce to an integer constant
case PORT_CLK_SEL_WRPLL1:
^~~~
......
Look here : https://lore.kernel.org/r/YkwQ6%2BtIH8GQpuct@zn.tnic
for the details why it happends.
