From: Borislav Petkov Date: Fri, 17 Jul 2009 23:55:16 +0000 (+0000) Subject: ide-tape: convert to ide_debug_log macro X-Git-Tag: 2.1b_release~11448^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e972d7027c0fb7055f5f2fe02d662c9528063bef;p=platform%2Fkernel%2Fkernel-mfld-blackbay.git ide-tape: convert to ide_debug_log macro Remove tape->debug_mask and use drive->debug_mask instead. There should be no functional change resulting from this patch. Signed-off-by: Borislav Petkov Signed-off-by: David S.
