Josh Cartwright c4b4ecbda5 ARM: msm: trout: fix uninit var warning
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.
