[PATCH] kernel-doc: handle spaces in array size

[Randy Dunlap <randy.dunlap@oracle.com>]

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

Unfortunately, kernel-doc has problems with a struct field like this:
	uint8_t databuf[NAND_MAX_PAGESIZE + NAND_MAX_OOBSIZE];

simply due to the spaces around the "+" sign, so drop all spaces inside
[...] so that parsing is done correctly (in some sense).

Warning(linux-2.6.20-git15/include/linux/mtd/nand.h:304): No description found for parameter 'NAND_MAX_OOBSIZE]'

This needs to sit in -mm for awhile to see if it has any adverse effects.

And yes, this is just a hack until kernel-doc learns to do better
parsing.
