Subject: mtd: nand: add helpers to access ->priv
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d39ddbd9ef70949bb78283a067e1b3366111dd90;p=linux-beck.git

mtd: nand: add helpers to access ->priv

Add two helpers to access the field reserved for private controller data.
This makes it clearer what this field is reserved for and ease future
refactoring.
