4.2.8-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>
commit fef586d58960bc867c1fa8126ee5d7364a5a89ac upstream.
In former commit, metering is supported for BeBoB based models
customized by M-Audio. The data in transaction is aligned to
big-endianness, while in the driver code u16 typed variable is assigned
to the data. This causes sparse warnings.
bebob_maudio.c:651:31: warning: cast to restricted __be16
bebob_maudio.c:651:31: warning: cast to restricted __be16
bebob_maudio.c:651:31: warning: cast to restricted __be16
bebob_maudio.c:651:31: warning: cast to restricted __be16
This commit fixes this bug by using __be16 variable for the data.
