Subject: ide: change order of register access in ide_config_drive_speed()
X-Git-Tag: v2.6.27-rc1~854^2~45
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c09384e95fa4048a06f179849901f3e57266d58;p=platform%2Fkernel%2Flinux-3.10.git

ide: change order of register access in ide_config_drive_speed()

Write ATA Feature register before ATA Sector Count register as
a preparation to use ->tf_load in ide_config_drive_speed().

This change shouldn't affect anything (just an usual paranoia).
