From: Linus Torvalds torvalds@linux-foundation.org
commit e7c6e405e171fb33990a12ecfd14e6500d9e5cf2 upstream.
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably "-Wstringop-overread" and "-Warray-parameter".
Both of them cause what seem to be valid warnings in the kernel, where we have array size mismatches in function arguments (that are no longer just silently converted to a pointer to element, but actually checked).
This fixes most of the trivial ones, by making the function declaration match the function definition, and in the case of intel_pm.c, removing the over-specified array size from the argument declaration.
At least one 'stringop-overread' warning remains in the i915 driver, but that one doesn't have the same obvious trivial fix, and may or may not actually be indicative of a bug.
[ It was a mistake to upgrade one of my machines to Fedora 34 while being busy with the merge window, but if this is the extent of the compiler upgrade problems, things are better than usual - Linus ]
