Subject: Re: [PATCH 11/15] ide: make ide_hwif_t.ide_dma_{host_off,off_quietly} void
[PATCH] ide: make ide_hwif_t.ide_dma_{host_off,off_quietly} void
* since ide_hwif_t.ide_dma_{host_off,off_quietly} always return '0'
make these functions void and while at it drop "ide_" prefix
* fix comment for __ide_dma_off_quietly()
* make __ide_dma_{host_off,off_quietly,off}() void and drop "__" prefix
v2:
* while at it rename atiixp_ide_dma_host_off() to atiixp_dma_host_off(),
sgiioc4_ide_dma_{host_off,off_quietly}() to sgiioc4_dma_{host_off,off_quietly}()
and sl82c105_ide_dma_off_quietly() to sl82c105_dma_off_quietly()
[ Noticed by Sergei Shtylyov <sshtylyov@...mvista.com>. ]
