[PATCH v3 1/4] PCI: sysfs: Define device attributes with DEVICE_ATTR*

Kelsey Skunberg
2019-08-15T15:37:26Z

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);
