From b0e370b95a3b231d0fb5d1958cce85ef57196fe6 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Tue, 11 Jun 2019 22:03:43 +0200 Subject: mmc: core: complete HS400 before checking status We don't have a reproducible error case, yet our BSP team suggested that the mmc_switch_status() command in mmc_select_hs400() should come after the callback into the driver completing HS400 setup. It makes sense to me because we want the status of a fully setup HS400, so it will increase the reliability of the mmc_switch_status() command.
