From 5601aaf73e5c2f0aa5e3607fee7b7d3511edfea9 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Wed, 30 Oct 2013 23:15:30 +0100 Subject: [PATCH] mmc: core: Remove unnecessary validations for bus_ops callbacks Due to the removal of the Kconfig option MMC_UNSAFE_RESUME, several validations of a present bus_ops callback became redundant. Let's remove these.
