I saw this while compiling the -rc3 kernel:
LD drivers/char/hw_random/built-in.o
CC drivers/char/ip2/ip2base.o
CC drivers/char/ip2/ip2main.o
drivers/char/ip2/i2ellis.c:100: warning: 'iiEllisCleanup' defined but not used
drivers/char/ip2/ip2main.c:3178: warning: 'ip2main_pci_tbl' defined but not used
LD drivers/char/ip2/ip2.o
LD drivers/char/ip2/built-in.o
I looked into it and it seems that in i2ellis.c:100 we have:
static void
iiEllisCleanup(void)
{
}
The strange thing is that that file gets included by drivers/char/ip2/ip2main.c
which does call it on line 431:
/* Cleanup the iiEllis subsystem. */
iiEllisCleanup();
But this call is inside:
#ifdef MODULE
void __exit
ip2_cleanup_module(void)
{
.....
}
#endif /* MODULE */
So when it is not compiled as a module (in this case it wasn't) the
function it includes is not needed or used. What would be the proper
way to fix this warning? The other warning about 'ip2main_pci_tbl' is
a little more complicated so I will ignore it for now but this one
still seems like it could be an easy fix.
