Subject: [PATCH 2/3] V4L: zc0301, remove bad usage of ERESTARTSYS
Date: Mon, 8 Oct 2007 08:34:14 -0400 [thread overview]
Message-ID: <11237258561195029635@pripojeni.net> (raw)
In-Reply-To: <21044149499772302@pripojeni.net>
zc0301, remove bad usage of ERESTARTSYS
down_read_trylock can't be interrupted and so ERESTARTSYS would reach
userspace, which is not permitted. Change it to EAGAIN
