I'm not planning to send anything to 4.19 anymore and this is so simple that hopefully it cause any conflicts with -next patches, so feel free to do that: Acked-by: Kalle Valo <kvalo@codeaurora.org>

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.
