From b717727ef25d4b73f73e3666341c07a034f908a6 Mon Sep 17 00:00:00 2001 From: Claudio Scordino Date: Tue, 9 Oct 2012 12:21:17 +0200 Subject: [PATCH] umc-bus.c: fix usage of device_trylock Fix usage of device_trylock. It has the same semantics of mutex_trylock, so it returns 1 if the lock has been acquired successfully.
