Subject: [PATCH 04/15] arm/omap: use generic_file_llseek in iommu_debug
Date: Tue, 14 Sep 2010 22:22:32 +0200 [thread overview]
Message-ID: <1284495763-7506-5-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1284495763-7506-1-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.
