Subject: ata: fix sparse warning in libata.h
From: Harvey Harrison <harvey.harrison@xxxxxxxxx>
Avoids lots of these, also is more readable.
include/linux/libata.h:1210:13: warning: potentially expensive pointer subtraction
Change the subtraction to addition on the other side of the comparison.
Thanks to Christer Weinigel for the suggestion.
