From 315781408ef4a6ff831f8fd37c90d4bb7c234853 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Mon, 22 Sep 2008 14:52:18 -0700 Subject: [PATCH] fs-enet: remove code associated with !CONFIG_PPC_MERGE 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().
