Subject: [PATCH 2/4] nvmem: core: Handle shift bits in-place if cell->nbits is non-zero
Date: Wed, 30 Sep 2015 13:35:15 +0100	[thread overview]
Message-ID: <1443616515-17763-1-git-send-email-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <1443616298-17389-1-git-send-email-srinivas.kandagatla@linaro.org>

From: Axel Lin <axel.lin@ingics.com>

It's pointless to test (cell->bit_offset || cell->bit_offset).
nvmem_shift_read_buffer_in_place() should be called when
(cell->bit_offset || cell->nbits).
