Subject: [PATCH] regmap: Fix build failure with CONFIG_DEBUG_FS=n

This fixes:

	drivers/base/regmap/regcache-rbtree.c: In function 'regcache_rbtree_init':
	drivers/base/regmap/regcache-rbtree.c:197: error: 'struct regmap' has no member named 'debugfs'
	drivers/base/regmap/regcache-rbtree.c:197: error: 'rbtree_fops' undeclared (first use in this function)
	drivers/base/regmap/regcache-rbtree.c:197: error: (Each undeclared identifier is reported only once
	drivers/base/regmap/regcache-rbtree.c:197: error: for each function it appears in.)

which was introduced by commit

	bad2ab4 (regmap: Provide debugfs dump of the rbtree cache data)

currently in next-20111122.
