Message-ID: <20110223043442.20795.4037.stgit@localhost6.localdomain6>
Date: Tue, 22 Feb 2011 21:34:42 -0700
From: Grant Likely <grant.likely@...retlab.ca>
To: Benjamin Herrenschmidt <benh@...nel.crashing.org>,
devicetree-discuss@...ts.ozlabs.org, sfr@...b.auug.org.au,

Cc: sparclinux@...r.kernel.org, linuxppc-dev@...ts.ozlabs.org
Subject: [RFC PATCH 13/15] dt/serial: Eliminate users of of_platform_{,
un}register_driver
Get rid of users of of_platform_driver in drivers/serial. The
of_platform_{,un}register_driver functions are going away, so the
users need to be converted to using the platform_bus_type directly.
Signed-off-by: Grant Likely <grant.likely@...retlab.ca>
