checkpatch: do not complain about positive return values starting with EPOLL
checkpatch complains about positive return values of poll functions.
Example:
WARNING: return of an errno should typically be negative (ie: return -EPOLLIN)
+ return EPOLLIN;
Poll functions return positive values. The defines for the return values
of poll functions all start with EPOLL, resulting in a number of false
positives. An often used workaround is to assign poll function return
values to variables and returning that variable, but that is a less than
perfect solution.
There is no error definition which starts with EPOLL, so it is safe to
omit the warning for return values starting with EPOLL.
