[PATCH 4.19 234/639] mmc: sdhci-brcmstb: handle mmc_of_parse() errors during probe

[Greg Kroah-Hartman]

From: Stefan Wahren <stefan.wahren@xxxxxxxx>

[ Upstream commit 1e20186e706da8446f9435f2924cd65ab1397e73 ]

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")
