Subject: [PATCH 4.18 12/44] mmc: core: Fix debounce time to use microseconds

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Lindgren <tony@...mide.com>

commit 1d71926bbd59facc4bdb6f13117d3a1aee8b83ba upstream.

The debounce value in device tree is in milliseconds but needs to be in
microseconds for mmc_gpiod_request_cd().

Fixes: bfd694d5e21c ("mmc: core: Add tunable delay before detecting card
after card is inserted")
