Re: [PATCH V2] Staging: wilc1000: Fix build break due to undeclared *wilc and implicit declaration of init_irq

[Dan Carpenter]

Top posting beucase I am a bad person.  Punit, you should have CC'd Glen
since this is his code.

The fix is still not right.  It will cause an unused variable warning on
some configs.

To be honest, this code makes no sense.  Why do we even have the wilc
variable in this function when we never use it?  Just declare move it to
wilc_netdev_init().  Also there are too many ifdefs in this code.

regards,
dan carpenter
