Subject: [PATCH -v2 11/16] PCI: frv: use generic pcibios_set_master()
Date: Fri, 28 Oct 2011 15:48:45 -0600	[thread overview]
Message-ID: <20111028214845.20088.99179.stgit@amt.stowe> (raw)
In-Reply-To: <20111028214726.20088.30551.stgit@amt.stowe>

From: Myron Stowe <mstowe@redhat.com>

This patch removes frv's architecture-specific 'pcibios_set_master()'
routine and lets the default PCI core based implementation handle PCI
device 'latency timer' setup.

No functional change.
