From eb6a5c3c020099bbbc41cf3509718828ec1733cc Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Mon, 26 Jun 2017 19:12:57 -0500 Subject: [PATCH] fs: use get_nand_dev_by_index() As part of preparation for nand DM conversion the new API has been introduced to remove direct access to nand_info array. So, use it here instead of accessing to nand_info array directly.
