[PATCH 0/2] vsprintf: Use __diag macros to disable '-Wsuggest-attribute=format'

[Nathan Chancellor]

Hi all,

This is a follow up to the complaint that Linus made at [1] about how
the #pragma and #ifdef to disable -Wsuggest-attribute=format is
currently ugly. Convert the #pragma and #ifdef to the existing __diag()
infrastructure in the kernel to hide some of the ugliness.

I am sending it to both the vsprintf maintainers/reviewers and Linus, in
case he wants to apply it himself (since it is pretty simple).
