Subject: drm/amdgpu: remove redundant null check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 3192f1d9b61a59d7c82fef187bffa7281fbdc9f5
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Remove the redundant null check since the caller ensures
that 'ctx' is never NULL.
