drm/amdgpu/gfx10: Avoid uninitialised variable 'index'
This stops clang complaining:
drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:3846:6: warning: variable 'index' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
if (ring->is_mes_queue) {
^~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:3903:30: note: uninitialized use occurs here
amdgpu_device_wb_free(adev, index);
^~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:3846:2: note: remove the 'if' if its condition is always false
if (ring->is_mes_queue) {
^~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/amd/amdgpu/gfx_v10_0.c:3839:16: note: initialize the variable 'index' to silence this warning
unsigned index;
