Subject: mtd/nand/sh_flctl: Replace the dangerous mtd_to_flctl macro
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=67026418;p=deliverable%2Flinux.git

mtd/nand/sh_flctl: Replace the dangerous mtd_to_flctl macro

The original macro worked only when applied to variables named 'mtd'.
While this could have been fixed by simply renaming the macro argument,
a more type-safe replacement is preferred.
