Hello.

Please always use Greg KH's latest staging-next branch (or -next)
to make these sorts of changes.  This one has already been done.

https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
$ cd staging
$ git checkout staging-next

And it might be nicer without the unnecessary parentheses too

	if (!wlandev || wlandev->msdstate != WLAN_MSD_RUNNING)
