[PATCH] mmc: mxs-mmc: Fix a resource leak in an error handling path in 'mxs_mmc_probe()'
From: Christophe JAILLET <hidden>
Date: 2020-12-08 20:37:33
Also in:
kernel-janitors, linux-mmc, lkml
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, the rest · Maintainers:
Ulf Hansson, Linus Torvalds
If 'mmc_of_parse()' fails, we must undo the previous 'dma_request_chan()'
call.
Fixes: abd37cccd47f ("mmc: mxs: use mmc_gpio_get_ro for detecting read-only status")
Signed-off-by: Christophe JAILLET <redacted>

I'm not 100% sure of the Fixes tag, but it seems to be the root cause. The
erroneous 'out_clk_disable' has then been kept around in the following
commits
