Subject: [PATCH resend 2/2] ide-h8300: remove custom tf_{read|load}() methods
Date: Wed, 1 Apr 2009 23:21:14 +0400	[thread overview]
Message-ID: <200904012321.14661.sshtylyov@ru.mvista.com> (raw)

Since tf_{read|load}() methods of this driver have now become identical to their
standard counterparts using I/O port accesses, there's no need to override those
anymore...

Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com>

The patch is against the current Linus' tree...
