In order to keep the code style consistency of the whole file, redundant return value ‘rc’ and its assignments should be deleted The clang_analyzer complains as follows: net/ieee802154/nl-mac.c:1203:12: warning: Although the value stored to 'rc' is used in the enclosing expression, the value is never actually read from 'rc' No functional change, only more efficient.
