+Subject: [PATCH] brcmfmac: avoid runtime-pm for sdio host controller
+
+Several host controllers supporting runtime-pm are causing issues
+with our sdio wireless cards because they disable the sdio interrupt
+upon going into runtime suspend. This patch avoids that by doing
+a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
+Duo 13 which uses sdhci-acpi host controller.
