Subject: [PATCH 05/18] arm/omap: use generic_file_llseek in iommu_debug
Date: Wed,  7 Jul 2010 23:40:07 +0200	[thread overview]
Message-ID: <1278538820-1392-6-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1278538820-1392-1-git-send-email-arnd@arndb.de>

In future kernels, debugfs files need to specify
the llseek operation explicitly to allow seeking.
This sets the llseek operation in the omap iommu
debugfs files to generic_file_llseek, which is
appropriate for files using simple_read_from_buffer.
