[PATCH] ip2main.c warning fixes
With Eric's "i386: Add a temporary to make put_user more type safe" patch we
get a pile of warnings out of ip2m1in.c:
drivers/char/ip2main.c: In function `ip2_ipl_ioctl':
drivers/char/ip2main.c:2910: warning: assignment makes integer from pointer without a cast
drivers/char/ip2main.c:2911: warning: assignment makes integer from pointer without a cast
drivers/char/ip2main.c:2912: warning: assignment makes integer from pointer without a cast
etc.
This ioctl is copying the kernel virtual address of a large number of
functions out to userspace. Heaven knows why.
Rather than fixing the warnings, I think we'll just nuke that code.
The patch also fixes a couple of `defined but not used' warnings.
