+Subject: mmc: sdhci-iproc: handle mmc_of_parse() errors during probe
+
+From: Stefan Wahren <stefan.wahren@i2se.com>
+
+commit 2bd44dadd5bfb4135162322fd0b45a174d4ad5bf upstream.
+
+We need to handle mmc_of_parse() errors during probe.
+
+This finally fixes the wifi regression on Raspberry Pi 3 series.
+In error case the wifi chip was permanently in reset because of
+the power sequence depending on the deferred probe of the GPIO expander.
+
+Fixes: b580c52d58d9 ("mmc: sdhci-iproc: add IPROC SDHCI driver")
