[PATCH AUTOSEL 4.19 03/21] mmc: mxs-mmc: Fix a resource leak in an error handling path in 'mxs_mmc_probe()'

[Sasha Levin]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 0bb7e560f821c7770973a94e346654c4bdccd42c ]

If 'mmc_of_parse()' fails, we must undo the previous 'dma_request_chan()'
call.
