drm/amdkfd: fix uint32 variable compared to less than zero
Currently the call to kfd_process_gpuidx_from_gpuid is returning an int value and this is being assigned to a uint32_t variable gpuidx and this is being checked for a negative error return which is always going to be false. Fix this by making gpuidx an int32_t. This makes gpuidx also type consistent with the use of gpuidx from the callers. Addresses-Coverity: ("Unsigned compared against 0") Fixes: cda0f85bfa5e ("drm/amdkfd: refine migration policy with xnack on") Signed-off-by: Colin Ian King <[email protected]> Reviewed-by: Felix Kuehling <[email protected]> Signed-off-by: Felix Kuehling <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
