Subject: iwlwifi: mvm: remove unneeded NULL pointer check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8dfc275109e794371c58be69e4286fa7061cd3a1;p=linux-beck.git

iwlwifi: mvm: remove unneeded NULL pointer check

mac80211 will never call rate_control_tx_status with a NULL
pointer for sta. Remove the superfluous check. This check
misled smatch.
