Subject: wifi: mwifiex: remove unnecessary queue empty check
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=659d609bdda5f9e96cbfaf8c4d0243277ca49d0f;p=linux-2.6-microblaze.git

wifi: mwifiex: remove unnecessary queue empty check

Since Commit 7bff9c974e1a ("mwifiex: send firmware initialization commands
synchronously") all initialization commands are sent synchronously which
means the command queue is empty when mwifiex_sta_init_cmd() returns. No
need to check for entries in the command code then, so remove the check.

Add a WARN_ON() just in case there is something wrong with the
reasoning.
