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); Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
