Subject: [PATCH 4.4 19/75] mmc: mxs-mmc: Fix a resource leak in an error handling path in mxs_mmc_probe()
From: Greg Kroah-Hartman <gregkh@...uxfoundation.org>
From: Christophe JAILLET <christophe.jaillet@...adoo.fr>
[ Upstream commit 0bb7e560f821c7770973a94e346654c4bdccd42c ]
If 'mmc_of_parse()' fails, we must undo the previous 'dma_request_chan()'
call.
