Subject: [PATCH v3 1/4] PCI: sysfs: Define device attributes with DEVICE_ATTR*
Defining device attributes should be done through the helper
DEVICE_ATTR_RO(), DEVICE_ATTR_WO(), or similar. Change all instances using
__ATTR* to now use its equivalent DEVICE_ATTR*.
Example of old:
static struct device_attribute dev_name_##_attr=__ATTR_RO(_name);
Example of new:
static DEVICE_ATTR_RO(_name);
