+Subject: [PATCH] brcmfmac: fix invalid access to struct acpi_device fields
+
+The fields of struct acpi_device are only known when CONFIG_ACPI is
+defined. Fix this by using a helper function. This will resolve the
+issue found in linux-next:
+
+ ../brcmfmac/bcmsdh.c: In function 'brcmf_ops_sdio_probe':
+ ../brcmfmac/bcmsdh.c:1139:7: error: dereferencing pointer to incomplete type
+ adev->flags.power_manageable = 0;
+ ^
+
+Fixes: f0992ace680c ("brcmfmac: prohibit ACPI power management ...")
