From 11e6831fd81468cf48155b9b3c11295c391da723 Mon Sep 17 00:00:00 2001 From: Maciej Andrzejewski maciej.andrzejewski@m-works.net Date: Mon, 2 Dec 2024 19:58:36 +0100 Subject: [PATCH] mtd: rawnand: arasan: Fix missing de-registration of NAND

The NAND chip-selects are registered for the Arasan driver during initialization but are not de-registered when the driver is unloaded. As a result, if the driver is loaded again, the chip-selects remain registered and busy, making them unavailable for use.
