From 83533ab28380f6957af39a7b322e639e42dbdaf1 Mon Sep 17 00:00:00 2001 From: Johan Rudholm Date: Mon, 12 Jan 2015 15:38:04 +0100 Subject: mmc: core: always check status after reset Always check if the card is alive after a successful reset. This allows us to remove mmc_hw_reset_check(), leaving mmc_hw_reset() as the only card reset interface.
