From d44154f969a44269a9288c274c1c2fd9e85df8a5 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Wed, 21 Sep 2016 11:44:41 +0200 Subject: mtd: nand: Provide nand_cleanup() function to free NAND related resources Provide a nand_cleanup() function to free all nand related resources without unregistering the mtd device. This should allow drivers to call mtd_device_unregister() and handle its return value and still being able to cleanup all nand related resources.
