Are the error codes positives on purpose?
checkpatch is throwing this warning:
USE_NEGATIVE_ERRNO: return of an errno should typically be negative (ie: return -ENOMEM)

Also the base code has a lot of these warnings:
RETURN_PARENTHESES: return is not a function, parentheses are not required

I guess you cannot do anything to avoid it in base code?
