checkpatch: handle EXPORT_SYMBOL for DEVICE_ATTR and similar
Handly definitions similar to below. The definition macro spits out a
symbol with a prefix. Add matching of any identifier prefix:
DEVICE_ATTR(link_power_management_policy, S_IRUGO | S_IWUSR,
ata_scsi_lpm_show, ata_scsi_lpm_put);
EXPORT_SYMBOL_GPL(dev_attr_link_power_management_policy);
