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

From: Chase Southwood
Date: Sun Aug 31 2014 - 15:45:24 EST


Sparse shows a couple of warnings like:

drivers/staging/comedi/drivers/usbduxsigma.c:787:23: warning: cast to restricted __be32

Looking at the indicated lines shows that the issue is caused by an
incorrect cast to uint32_t instead of __be32. Fix this cast.
