Subject: [PATCH] wifi: iwlwifi: mvm: initialize seq variable
Git-commit: 11e94d2bcd88dea5d9ce99555b6b172f5232d3e2

Clang static analysis reports this issue
d3.c:567:22: warning: The left operand of '>' is
a garbage value
if (seq.tkip.iv32 > cur_rx_iv32)
~~~~~~~~~~~~~ ^
seq is never initialized. Call ieee80211_get_key_rx_seq() to
initialize seq.
