From 103cb4e1e8762fb39d1121e269f758db45071e13 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Thu, 30 Oct 2008 00:16:04 +0000 Subject: anysee: initialize anysee_usb_mutex statically From: Akinobu Mita anysee_usb_mutex is initialized at every time the anysee device is probed. If the second anysee device is probed while anysee_usb_mutex is locked by the first anysee device, the mutex is broken. This patch fixes by initialize anysee_usb_mutex statically rather than initialize at probe time.
