Subject: [PATCH] net/ieee802154: drop unneeded assignment in llsec_iter_devkeys()
Date: Sun, 25 Apr 2021 18:24:59 +0800 [thread overview]
Message-ID: <1619346299-40237-1-git-send-email-yang.lee@linux.alibaba.com> (raw)
[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain; charset=n, Size: 1486 bytes --]
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.
