Subject: firewire: nosy: fix list corruption by NOSY_IOC_STOP
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a2d39db9dec0e7e403f54c9cf98b7dbc82b4c44a;p=linux-beck.git

firewire: nosy: fix list corruption by NOSY_IOC_STOP

nosy_stop_snoop() would blow up the second time it was called without
nosy_start_snoop() in between.
