From: Sergei Shtylyov Date: Mon, 9 Jul 2007 21:17:54 +0000 (+0200) Subject: ide: make void and rename ide_dma_timeout() method X-Git-Tag: v2.6.23-rc1~1224 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c283f5dbe31920ca70b80a594a97bfaa2a28be13;p=linux-2.6 ide: make void and rename ide_dma_timeout() method Since ide_dma_timeout() method's result is discarded, make it return 'void'. While at it, drop 'ide_' from the method's name, drop the '__' prefix from the default method's name, and do some cleanups in this method driver-wise: - in ide-dma.c, au1xxx-ide.c, and pdc202xx_old.c, define/use 'hwif' variable; - in au1xxx-ide.c, get rid of commented out printk(); - in sl82c105.c, get rid of unnecessary variables.
