+# include modules to support unlocking FDE (touchscreen, panel, etc),

+# The format is one module name per line. Lines starting with the character

+Subject: [PATCH] ARM: 8933/1: replace Sun/Solaris style flag on section
+ directive
+
+It looks like a section directive was using "Solaris style" to declare
+the section flags. Replace this with the GNU style so that Clang's
+integrated assembler can assemble this directive.
+
+The modified instances were identified via:

+
+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.
