Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 2338 Lines: 52 when compiling with allmodconfig, CONFIG_64BIT=y the file drivers/base/regmap/regmap-mmio.c will use readq and writeq. so we need implement these functions. BTW: the coding style can not pass ./scripts/checkpatch.pl. it seems better to provide additional patch for beautifying code.
