I'd just keep this static inside the HID HAL since that seems to be the
only user for it. Actually I'm not even convinced that it's worth to
have this as a separate function since you only have two users and
essentially the function is just two lines (the if-statement is
redundant). Also, the function name isn't quite right. You're converting
from hex to binary. Not from ascii to hex (hex notation is already using
the ascii character set). Also, do consider the point from Jerzy about
the format specifier.
