+Subject: [PATCH] brcmfmac: fix suspend/resume when power is cut off
+
+brcmfmac assumed the wifi device always remains powered on and thus
+hardcoded the MMC_PM_KEEP_POWER flag expecting the wifi device to
+remain on even during suspend/resume cycles.
+
+This is not always the case, some appliances cut power to everything
+connected via SDIO for efficiency reasons and this leads to wifi not
+being usable after coming out of suspend because the device was not
+correctly reinitialized.
+
+So we check for the keep_power capability and if it's not present then
+we remove the device and probe it again during resume to mirror what's
+happening in hardware and ensure correct reinitialization in the case
+when MMC_PM_KEEP_POWER is not supported.

+Make sure to use the current alternate setting when verifying the

+
+Failing to do so could cause the driver to misbehave or trigger a WARN()
