From: Paul Bolle Date: Sun, 4 May 2014 11:50:29 +0000 (+0200) Subject: libata-sff: remove dead code X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a96120c40c334bb43fc93bb1d30ff409ad0cb1dd;p=karo-tx-linux.git libata-sff: remove dead code Ever since v2.6.19 the code contains a check for CONFIG_NO_ATA_LEGACY. But that macro has never been defined. Apparently no one ran into problems on platforms that do not support compatibility mode. So remove this code that has been dead for over seven years.
