From: Bartlomiej Zolnierkiewicz Date: Fri, 1 Feb 2008 22:09:20 +0000 (+0100) Subject: ide-cd: remove redundant config flags X-Git-Tag: firefly_0821_release~23571^2~78 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3f1b86d89dc73dedda426a85e600ad244ed9fad4;p=firefly-linux-kernel-4.4.55.git ide-cd: remove redundant config flags * Use CDC_* flags directly and remove redundant flags from ->config_flags. While at it: * Add KERN_CONT to printk()-s in ide_cdrom_probe_capabilities().
