[PATCH 1/3] regmap: cache: regcache_hw_init() should use regmap_bulk_read()

From: Doug Anderson
Date: Fri Jun 27 2014 - 15:58:34 EST


We really should be using regmap_bulk_read() in regcache_hw_init().
The regmap_bulk_read() will translate into regmap_raw_read() when
appropriate. Doing this fixes problems where regmap_smbus() will
crash because they don't implement .read and .write.
