Subject: ASoC: adau1701: fix adau1701_reg_read()
From: Daniel Mack <zonque@xxxxxxxxx>
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.
