Subject: mac80211: remove redundant initialization to pointer 'hdr'
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=11b05ba34d89808ca99180d2656438a319670c56;p=openwrt%2Fstaging%2Fblogic.git

mac80211: remove redundant initialization to pointer 'hdr'

The pointer hrd is being initialized with a value that is never read
and re-assigned a little later, hence the initialization is redundant
and can be removed.

Cleans up clang warning:
net/mac80211/tx.c:1924:24: warning: Value stored to 'hdr' during its
initialization is never read
