Summary:                    [patch] zaptel.c has unchecked calls to
copy_from_user() and copy_to_user()
Description: 
In zaptel.c, some invocations of copy_from_user() and copy_to_user() do not
have their return value checked, which results in compiler warnings when
compiling under Linux 2.6 (see below).

Also, some calls which are checked, return -EIO as the error code instead
of -EFAULT.

The attached patch corrects both of the above.
