Checkpatch flags CamelCase identifiers in strict mode, but it has a
feature to ignore parts with only two characters to allow for SI units
like mV or uA. Unfortunately, not all SI units fit in two characters,
and not all are lower case followed by upper case.
This patch changes the check from [a-z][A-Z] to [a-zA-Z]{1,3} (any
combination of up to three lower and upper case characters), so that it
will also allow units like MHz, As or KiB.
