Subject[PATCH] staging: comedi: usbdux: fix sparse endianness warnings
Date
Sparse has many warnings like:

drivers/staging/comedi/drivers/usbdux.c:366:32: warning: cast to
restricted __le16

on lines on which devpriv->in_buf or devpriv->insn_buf are passed to
le16_to_cpu(). This suggests that both of these variables should actually
be of type __le16.

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.
