Subject: [PATCH 4.8 73/92] mmc: sdhci-msm: Fix error return code in sdhci_msm_probe()

4.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <weiyongjun1@...wei.com>

commit d1f63f0c81c22ba705fcd149a1fcec37b734d818 upstream.

Fix to return a negative error code from the platform_get_irq_byname()
error handling case instead of 0, as done elsewhere in this function.

Fixes: ad81d3871004 ("mmc: sdhci-msm: Add support for UHS cards")
