Subject: [PATCH] mmc: wmt-sdmmc: remove an incorrect release_mem_region() call in the .remove function
Date: Mon, 26 Feb 2024 22:37:39 +0100	[thread overview]
Message-ID: <bb0bb1ed1e18de55e8c0547625bde271e64b8c31.1708983064.git.christophe.jaillet@wanadoo.fr> (raw)

This looks strange to call release_mem_region() in a remove function
without any request_mem_region() in the probe or "struct resource"
somewhere.

So remove the corresponding code.

Fixes: 3a96dff0f828 ("mmc: SD/MMC Host Controller for Wondermedia WM8505/WM8650")
