Subject[PATCH 02/10] drm/amdgpu: Remove tmp unused variable
Date
The variable tmp is not used in the dce_v6_0_hpd_fini and
dce_v8_0_hpd_fini functions. Therefor, the variable is removed in order to
avoid the following Clang warnings:

drivers/gpu/drm/amd/amdgpu/dce_v6_0.c:331:6: warning: variable 'tmp' set but
not used [-Wunused-but-set-variable]
u32 tmp;
^
drivers/gpu/drm/amd/amdgpu/dce_v8_0.c:325:6: warning: variable 'tmp' set but
not used [-Wunused-but-set-variable]
u32 tmp;
^
