Subject: sfc: use DEVICE_ATTR_*() macro
X-Git-Tag: microblaze-v5.15~120^2~471
X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;ds=sidebyside;h=3880fc37beba5d6878ef4c8d57f21683974a211b;p=linux-2.6-microblaze.git

sfc: use DEVICE_ATTR_*() macro

Use DEVICE_ATTR_*() helper instead of plain DEVICE_ATTR,
which makes the code a bit shorter and easier to read.
