Re: [PATCH] drm/amdkfd: remove unused function get_reserved_sdma_queues_bitmap

[Felix Kuehling]

[+Mukul]

Looks like this problem was introduced by Mukul's patch "drm/amdkfd: 
Update SDMA queue management for GFX9.4.3". Could this be a merge error 
between GFX 9.4.3 and GFX11 branches? I think the 
reserved_sdma_queues_bitmap was introduced after the 9.4.3 branch was 
created. Mukul, you worked on both, so you're probably in the best 
position to resolve this.
