From 24f5aec3646f2a22d8ff8e02c07d6c9a92a5092a Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 6 Sep 2016 22:17:32 +0900 Subject: [PATCH] mmc: squash lines for immediate return These functions can be much simpler by squashing lines for immediate return. For *_bind() callbacks, they will be a simple wrapper function of an upper-level bind API. For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of mmc_switch().
