Subject: [PATCH] mmc: core: Fix debounce time to use microseconds
Date: Tue, 18 Sep 2018 16:16:56 -0700 [thread overview]
Message-ID: <20180918231656.21778-1-tony@atomide.com> (raw)
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")
