Subject: e100: Do suspend/shutdown like e1000
X-Git-Tag: v2.6.25-rc6~31^2~41
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=f902283bbe68639142a00dd23d80ee31e1b00759;p=linux-2.6-omap-h63xx.git

e100: Do suspend/shutdown like e1000

This fixes a "trying to free already free IRQ" message and simplifies
the shutdown/suspend code by re-using already existing code when going
to suspend. The code is now symmetric with e100_resume.
