[PATCH 0/3] Fix GCC 12 build error

[Michael Chang]

The tested gcc version is:

 abuild@mazu:~> gcc --version
 gcc (SUSE Linux) 12.0.1 20220307 (experimental) [revision 
40c1d4a07e5798c01e4364336c9617550744861d]

Although it may not catch all build errors as there are quite many
combinations of cpu architecture and platform which grub supports. The
work is as far as I can get right now and I'd like to have them reviewed
before anyone running into similar problems.

Thanks,
Michael
