Staging: bcm: Fix semaphore locking bug in, IOCTL_BCM_BUFFER_DOWNLOAD
In this ioctl, we are testing to see if the lock is held. If it is not held, that means this ioctl used incorrectly. Therefore, we do not want to take the lock ourselves here. Signed-off-by: Kevin McKinney <klmckinney1@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
