Subject: [PATCH 1/3] regmap: cache: regcache_hw_init() should use regmap_bulk_read()
Date: Fri, 27 Jun 2014 12:56:11 -0700	[thread overview]
Message-ID: <1403898973-19571-2-git-send-email-dianders@chromium.org> (raw)
In-Reply-To: <1403898973-19571-1-git-send-email-dianders@chromium.org>

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.
