Subject: staging: comedi: comedi_compat_ioctl should be NULL not 0
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=55232eca66c540cbef9b950e71b358137651955b;p=linux-beck.git

staging: comedi: comedi_compat_ioctl should be NULL not 0

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
