The for-loop condition does not work correctly on architectures where "char"
is unsigned. Fix it by using an "int", which may also result in more
efficient code.

Thanks, applied to wireless-drivers-next.git.

Thanks,

The for-loop condition does not work correctly on architectures where
"char" is unsigned. Fix it by using an "int", which may also result in
more efficient code.
v2: Remove unneeded initialization.

But afterwards I removed the change log. That doesn't belong to the
commit log, please add that after "---" line separator.
Also in patchwork your name has (ELSOFT AG), I edited that out.

This change is OK, but as long as you are touching this line, you should remove
the initialization to zero. The first executable statement of that routine is
"for (i = 3; i >= 0; --i)", thus there is no possibility that the variable could
be used without being initialized.
Thanks,
