Subject: [PATCH] fix fatal kernel-doc error

From: Randy Dunlap <randy.dunlap@...cle.com>

Teach kernel-doc to handle functions that look like the new
pcim_iomap_table().  Fixes this fatal error in scripts/kernel-doc:

  DOCPROC Documentation/DocBook/kernel-api.xml
Error(/tester/linsrc/linux-2.6.20-git6//drivers/pci/pci.c:1351): cannot understand prototype: 'void __iomem * const * pcim_iomap_table(struct pci_dev *pdev) '
make[1]: *** [Documentation/DocBook/kernel-api.xml] Error 1
make: *** [htmldocs] Error 2
