Subject: [patch 11/21] fs-enet: remove code associated with !CONFIG_PPC_MERGE
From: Kumar Gala <galak@...nel.crashing.org>
Now that arch/ppc is gone we don't need CONFIG_PPC_MERGE anymore remove
the dead code associated with !CONFIG_PPC_MERGE.
With this change the pre_request_irq() and post_free_irq() calls became
nops so they have been removed. Also removed fs_request_irq() and
fs_free_irq() and just called request_irq() and free_irq().
