Thank you, Linus already dropped problematic changes.

This apparently comes from c0c8dd0a7773 ("pinctrl: core: Add a
convenient define PINCTRL_GROUP_DESC()") and following patches
from Andy Shevchenko (added to Cc).
I also checked different compiler versions and found that the
new code works fine with gcc-13.2.0, but not with gcc-12 or
older.
