From f45ebc8a06e76075a4e5f57950adfaac1f48c1db Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Sun, 1 May 2016 22:58:19 +0200 Subject: [PATCH] UPSTREAM: stmmac: let remove/resume/suspend functions take device pointer Change stmmac_remove/resume/suspend to take a device pointer so they can be used directly by drivers that doesn't need to perform anything device specific. This lets us remove the PCI pm functions and later simplifiy the platform drivers. Signed-off-by: Joachim Eastwood Tested-by: Marek Vasut Signed-off-by: David S.
