Subject: [PATCH 16/19] sis5513: sis5513_config_xfer_rate() cleanup
Date: Fri, 12 Jan 2007 05:27:47 +0100	[thread overview]
Message-ID: <20070112042747.28794.38484.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070112042621.28794.6937.sendpatchset@localhost.localdomain>

[PATCH] sis5513: sis5513_config_xfer_rate() cleanup

* remove bogus comment for sis5513_config_xfer_rate()
* there is no need to call config_drive_art_rwp() because
  it is called by config_art_rwp_pio()
* remove needless wrapper
* remove stale "TODO" comment
  (IDE core should provide generic tuning code)
