Subject: iwlwifi: mvm: compare full command ID
X-Git-Tag: v4.9-rc1~127^2~35^2~7^2~31
X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=61b0f5d7c41408ff523a5cd3925feafa82b971f5

iwlwifi: mvm: compare full command ID

When comparing command IDs, the group should be taken
into account so the same command/notification from a
different group doesn't trigger anything unexpected.
Fix this by comparing to the wide ID.

Fixes: commit 1738d60b31d7 ("iwlwifi: mvm: handle RX MPDUs separately")
