Subject: [PATCH 1/7] arm: mach-omap: Change file flags in emmc handler
Date: Fri, 28 Apr 2017 14:46:02 +0200	[thread overview]
Message-ID: <1493383568-27798-1-git-send-email-d.schultz@phytec.de> (raw)

This handler tries to read from a file descriptor with 'write only'
flags and fails. Add read permissions for the file, so the handler can
read the partition layout.
