linux-next: manual merge of the drm tree with the drm-fixes tree

From: Mark Brown

Date: Fri Apr 03 2026 - 09:34:07 EST

Hi all,

Today's linux-next merge of the drm tree got conflicts in:

drivers/gpu/drm/amd/pm/swsmu/smu11/smu_v11_0.c
drivers/gpu/drm/amd/pm/swsmu/smu12/smu_v12_0.c
drivers/gpu/drm/amd/pm/swsmu/smu14/smu_v14_0.c

between commit:

a3ffaa5b397f4 ("drm/amdgpu/pm: drop SMU driver if version not matched messages")

from the drm-fixes tree and commits:

6b0a6116286ef ("drm/amd/pm: Unify version check in SMUv11")
353f200825051 ("drm/amd/pm: Unify version check in SMUv12")
964e532d58378 ("drm/amd/pm: Unify version check in SMUv14")

from the drm tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
