Subject: [PATCH] ipw2x00: make ipw_setup_deferred_work() void
This function actually needs no return value. So remove the unneeded
variable 'ret' and make it void.
This also fixes the following coccicheck warning:
drivers/net/wireless/intel/ipw2x00/ipw2200.c:10648:5-8: Unneeded
variable: "ret". Return "0" on line 10684
