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;
|
|
^
|
|
|
