Subject[PATCH next] drm/amdgpu: Fix unsigned comparison with zero in gmc_v9_0_process_interrupt()
Date
Smatch warns:
drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c:579:
unsigned 'xcc_id' is never less than zero.

gfx_v9_4_3_ih_to_xcc_inst() returns negative numbers as well.
Fix this by changing type of xcc_id to int.

Fixes: faf96b9b602d ("drm/amdgpu: correct the vmhub index when page fault occurs")
