Hi.
The following patch makes a 'defined but not used' warning go
away when compiling drivers/net/irda/w83977af_ir.c without
modular support (kernel 240t12p7). It also removes some unneeded
zero initializations.

By reading my mind, I guess :( The following updated patch should fix this.
Thanks for the catch.
