From 618aa1068df29c37a58045fe940f9106664153fd Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Tue, 19 Mar 2013 09:21:07 +0100 Subject: [PATCH] USB: garmin_gps: fix memory leak on disconnect 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.
