From: James Bottomley Date: Sun, 24 Apr 2011 19:31:33 +0000 (-0500) Subject: libata-sff: prevent irq descriptions for dummy ports X-Git-Tag: firefly_0821_release~7613^2~1365^2~6 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=af649a1b56032a84b75825a94204a8f8f0120698;p=firefly-linux-kernel-4.4.55.git libata-sff: prevent irq descriptions for dummy ports This is a cosmetic change to prevent libata-sff adding irq descriptions to dummy ports, since the information, while largely unused, is erroneous.
