Subject: USB: garmin_gps: fix memory leak on disconnect
From: Johan Hovold <jhovold@xxxxxxxxx>
commit 618aa1068df29c37a58045fe940f9106664153fd upstream.
Remove bogus disconnect test introduced by 95bef012e ("USB: more serial
drivers writing after disconnect") which prevented queued data from
being freed on disconnect.
The possible IO it was supposed to prevent is long gone.
