Commit Message

Artur Weber May 23, 2023, 9:20 p.m. UTC 
Fixes compilation errors on older GCC versions (before 8.x) and Clang
after changes introduced in commit 6810bb390282 ("drm/panel: Add
Samsung S6D7AA0 panel controller driver"). Tested with GCC 13.1.1,
GCC 6.4.0 and Clang 16.0.3.

Hi Artur,
Thanks for the patch! Mind sending a v2 with the diagnostic added to
the commit message? This gives reviewers much more context as to what
issue you are fixing.

Perhaps it was these errors:
https://lore.kernel.org/llvm/646c6def.a70a0220.58c1a.903d@mx.google.com/T/#u

?
If so, please add

Reported-by: kernelci.org bot <bot@kernelci.org>
Link: https://lore.kernel.org/llvm/646c6def.a70a0220.58c1a.903d@mx.google.com

To the v2 commit message as well.
