From b37a9208a2ed36b67303e8169539c1a0c42ea0e1 Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Sat, 4 Nov 2023 16:37:48 -0400 Subject: [PATCH] mtd: Add some fallbacks for add/del_mtd_device This allows using these functions without ifdefs. OneNAND depends on MTD, so this ifdef was redundant in the first place.
