It was a casual grep and the comment should probably be improved anyway. <insert appropriate emoji here> cheers, Joe

The BIT macro isn't available in userspace. Checkpatch complains about shifts being used instead of the macro and people are starting to send patches without realizing that it's a UAPI header file. Hence let's replace the BIT macro with a hex values to make everyone happy.
