[PATCH] staging: comedi: comedi_compat_ioctl should be NULL not 0

From: H Hartley Sweeten
Date: Mon Jun 18 2012 - 19:54:06 EST


When CONFIG_COMPAT is not defined, comedi_compat_ioctl should be
NULL not 0 in order to set the file_operations compat_ioctl variable
correctly.

This quiets a sparse warning about:

warning: Using plain integer as NULL pointer
