Subject: [PATCH] pcmcia: ds: fix suspend/resume
Date: Sun, 21 Aug 2016 00:05:30 +0100 [thread overview]
Message-ID: <E1bbFKU-0001OO-RA@rmk-PC.armlinux.org.uk> (raw)
PCMCIA suspend/resume no longer works since the commit mentioned below,
as the callbacks are no longer made. Convert the driver to the new
dev_pm_ops, which restores the suspend/resume functionality. Tested on
the arm arch Assabet platform with a pcnet_cs CF card.
Fixes: aa8e54b559479 ("PM / sleep: Go direct_complete if driver has no callbacks")
Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
