[PATCH 2/4] nvmem: core: Handle shift bits in-place if cell->nbits is non-zero

From: Srinivas Kandagatla
Date: Wed Sep 30 2015 - 08:36:10 EST


From: Axel Lin <axel.lin@xxxxxxxxxx>

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).
