Subject: drm/amdgpu: increase max instance number for hw ip
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c8ff09bf41f851e6e9bb2a9f8353f6c78f80f3c1;p=linux.git

drm/amdgpu: increase max instance number for hw ip

max instance number is 6 for navi10 and 7 for navi14, and we increase the
reg_offset array size to avoid out-of-bound access
