Subject: [PATCH 12/15] ide: make ide_hwif_t.ide_dma_host_on void
Date: Fri, 19 Jan 2007 01:32:20 +0100	[thread overview]
Message-ID: <20070119003220.14846.14258.sendpatchset@localhost.localdomain> (raw)
In-Reply-To: <20070119003058.14846.43637.sendpatchset@localhost.localdomain>

[PATCH] ide: make ide_hwif_t.ide_dma_host_on void

* since ide_hwif_t.ide_dma_host_on is called either when drive->using_dma == 1
  or when return value is discarded make it void, also drop "ide_" prefix
* make __ide_dma_host_on() void and drop "__" prefix
