[PATCH 3.16.y-ckt 102/126] ALSA: bebob: use correct type for __be32 data

From: Luis Henriques
Date: Wed Dec 09 2015 - 04:52:21 EST


3.16.7-ckt21 -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.
