Date: Mon, 15 Sep 2014 15:07:48 -0700 From: Kamal Mostafa <kamal@...onical.com> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org, kernel-team@...ts.ubuntu.com Cc: Daniel Mack <zonque@...il.com>, Mark Brown <broonie@...aro.org>, Kamal Mostafa <kamal@...onical.com> Subject: [PATCH 3.13 058/187] ASoC: adau1701: fix adau1701_reg_read() 3.13.11.7 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Daniel Mack <zonque@...il.com> commit 3ad80b828b2533f37c221e2df155774efd6ed814 upstream. Fix a long standing bug in the read register routing of adau1701. The bytes arrive in the buffer in big-endian, so the result has to be shifted before and-ing the bytes in the loop.
