Subject: [PATCH 1/7] ARM: msm: trout: fix uninit var warning

From: Josh Cartwright <joshc@...eaurora.org>

Fix the following warning when !CONFIG_MMC:

arch/arm/mach-msm/board-trout.c: In function 'trout_init':
arch/arm/mach-msm/board-trout.c:67:6: warning: unused variable 'rc' [-Wunused-variable]
  int rc;
      ^

Also, while we're here, rework explicit printk(KERN_CRIT..) to use
pr_crit.
