From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 6052b3c370fb82dec28bcfff6d7ec0da84ac087a ]
A call to 'ausdhi6_dma_release()' to undo a previous call to
'usdhi6_dma_request()' is missing in the error handling path of the probe
function.
It is already present in the remove function.
Fixes: 75fa9ea6e3c0 ("mmc: add a driver for the Renesas usdhi6rol0 SD/SDIO host controller")
