Prev: [PATCH] mtd: Replace the dangerous to_fsl_upm_nand macro with an inline function
Next: [PATCH] mtd: Replace the dangerous mtd_to_flctl macro with an inline function
From: Ferenc Wagner on 23 Mar 2010 13:10 The original macro worked only when applied to variables named 'evt'. While this could have been fixed by simply renaming the macro argument, a more type-safe replacement is preferred.
