Subject: [PATCH] drm/amd/pm: use bitmap_{from,to}_arr32 where appropriate
Git-commit: 525d6515604eb1373ce5e6372a6b6640953b2d6a
Patch-mainline: v5.19-rc1
References: git-fixes

The smu_v1X_0_set_allowed_mask() uses bitmap_copy() to convert
bitmap to 32-bit array. This may be wrong due to endiannes issues.
Fix it by switching to bitmap_{from,to}_arr32.
