[PATCH 6.0 404/862] mmc: wmt-sdmmc: Fix an error handling path in wmt_mci_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit cb58188ad90a61784a56a64f5107faaf2ad323e7 ]

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")
