Subject: wireless, airo: waitbusy() won't delay
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b7acbdfbd1f277c1eb23f344f899cfa4cd0bf36a;p=openwrt%2Fstaging%2Fblogic.git

wireless, airo: waitbusy() won't delay

There will be no delay even when COMMAND_BUSY (defined 0x8000) is set:
0x8000 & (delay < 10000) will evaluate to 0 - when delay is 0.
