From 5dbabace4f8514500c729d3e4fe10b2811a35f15 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 21 Mar 2013 12:37:49 +0100 Subject: [PATCH] USB: garmin_gps: remove bogus disconnect test in bulk callback Remove bogus disconnect test for serial device being NULL in read bulk callback. This can never happen as the port read urb is killed (and poisoned) at close, which in turn is guaranteed to be called before the last tty reference is dropped (and port->serial is cleared).
