Subject: [PATCH] mmc: sdhci-brcmstb: handle mmc_of_parse() errors during probe
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")
