Hi Quite right! I found this error in some of the files. And after discussion with Larry Finger and Peter Wu, it was decided that all files with this if statement should change. But of course I should update the comment to something more suitable.

Right, do not forget to use [PATCH v2] as prefix and adjust the subject too as this is no longer just "cleaning up a statement that always evaluates to false", but rather "fix [insert stuff here] mask" (for the 0xfc cases). The commit message must describe why the change is beneficial, see other commit messages for examples.

I find a logical error in an if statement '(X & 0xfc) == 0x3' is always false After pointing this out, Larry Finger informed what would be the correct one.
