3.16.62-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Mack <daniel@xxxxxxxxxx>
commit 4f666675cdff0b986195413215eb062b7da6586f upstream.
When powering down a SDIO connected card during suspend, make sure to call
into the generic lbs_suspend() function before pulling the plug. This will
make sure the card is successfully deregistered from the system to avoid
communication to the card starving out.
