[PATCH] net/ieee802154: drop unneeded assignment in llsec_iter_devkeys()

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

 



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.
