[PATCH 2/2] mmc: sdhci-brcmstb: handle mmc_of_parse() errors during probe
From: Stefan Wahren <hidden>
Date: 2018-12-23 21:00:44
Also in:
linux-mmc
Subsystem:
multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) broadcom brcmstb driver, secure digital host controller interface (sdhci) driver, the rest · Maintainers:
Ulf Hansson, Kamal Dasu, Al Cooper, Adrian Hunter, Linus Torvalds
We need to handle mmc_of_parse() errors during probe otherwise the
MMC driver could start without proper initialization (e.g. power sequence).
Fixes: 476bf3d62d5c ("mmc: sdhci-brcmstb: Add driver for Broadcom BRCMSTB SoCs")

Hi,
since i don't have this hardware, so it is only compile tested.
Would be nice to get a Tested-by.
Regards
Stefan
