Subject: [TG3]: Save MSI state before suspend.
X-Git-Tag: upstream/snapshot3+hdmi~35992^2~2^2~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=436f137975507b0baab0859a253c3c9332c22f62;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

[TG3]: Save MSI state before suspend.

This fixes the following problem:

http://bugzilla.kernel.org/show_bug.cgi?id=7969

The MSI state needs to be saved during suspend.  PCI state saved
during tg3_init_one() does not contain valid MSI state because
MSI hasn't been enabled.
