Subject: [PATCH] mmc: wmt-sdmmc: Fix an error handling path in wmt_mci_probe()
Date: Sun,  6 Mar 2022 18:44:56 +0100	[thread overview]
Message-ID: <bf2e2e69226b20d173cce66287f59488fd47474b.1646588375.git.christophe.jaillet@wanadoo.fr> (raw)

A dma_free_coherent() call is missing in the error handling path of the
probe, as already done in the remove function.

Fixes: 3a96dff0f828 ("mmc: SD/MMC Host Controller for Wondermedia WM8505/WM8650")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
---
I've not been able to find a Fixes tag because of the renaming of
function and files.
However, it looks old (before 2008)
