Subject: [PATCH 2/5] usb: gadget: f_mass_storage: If 'ro'/'cdrom' specified, open file as read-only
Date: Tue, 5 Apr 2011 18:36:39 +0300 [thread overview]
Message-ID: <1302017802-16614-3-git-send-email-roger.quadros@nokia.com> (raw)
In-Reply-To: <1302017802-16614-1-git-send-email-roger.quadros@nokia.com>
If we don't need Write access then attempt to open backing file in Read Only
mode instead of bailing out too soon.
