Subject: wl1271: check result code from the join command
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=cd264769f7a571fc2a61765757ed85c56f02e9d3;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

wl1271: check result code from the join command

We were not checking the return value from the call to wl1271_cmd_join().
Added a check to make things more reliable.
