[PATCH v5 12/21] modpost: unify 'sym' and 'to' in default_mismatch_handler()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



find_tosym() takes 'sym' and stores the return value to another
variable 'to'. You can use the same variable because we want to
replace the original one when appropriate.
