Subject: [PATCH 1/2] at91_ide: remove custom tf_{ead|load}() methods
Date: Wed, 1 Apr 2009 23:17:48 +0400 [thread overview]
Message-ID: <200904012317.48069.sshtylyov@ru.mvista.com> (raw)
Since tf_{read|load}() methods of this driver have now become identical to their
standard counterparts using MMIO accesses, there's no need to override those
anymore...
Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com>
