[PATCH] remove some more check_region stuff
Removed some more references to check_region(). I checked these changes into the 'checkreg' branch of rsync://rsync.kernel.org/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git The only valid references remaining are in: drivers/scsi/advansys.c drivers/scsi/BusLogic.c drivers/cdrom/sbpcd.c sound/oss/pss.c Remove last vestiges of ide_check_region() drivers/char/specialix: trim trailing whitespace drivers/char/specialix: eliminate use of check_region() Remove outdated and unused references to check_region() [sound oss] remove check_region() usage from cs4232, wavfront [netdrvr eepro] trim trailing whitespace [netdrvr eepro] remove check_region() usage Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
