[PATCH] staging: comedi: usbduxsigma: fix sparse endianness warnings

From: Chase Southwood
Date: Fri Aug 29 2014 - 21:41:15 EST


Sparse has many warnings like:

drivers/staging/comedi/drivers/usbduxsigma.c:293:21: warning: cast to
restricted __be32

on lines on which devpriv->in_buf is passed to be32_to_cpu(). This
suggests that this variable should actually be of type __be32.

This is, as usual, compile tested only. I tried to verify as best as I
could that this is a sane change, but I am unable to test on the hardware.
