Perhaps space aligned declarations should have some
checkpatch --strict warning for 2 or more spaces
around any assignment of the declaration.
int a = 1; // 2+ spaces before =
int b = 2; // 2+ spaces after =
int c = 3; // uses tabs around =, no warning
int d = 4; // uses 2 tabs before =, no warning
Something like:
