Subject: [PATCH] sh: Eliminate unused irq_reg_{readl,writel} accessors
From: Kevin Cernekee <cernekee@...il.com>
Defining these macros way down in arch/sh/.../irq.c doesn't cause
kernel/irq/generic-chip.c to use them. As far as I can tell this code
has no effect.
Signed-off-by: Kevin Cernekee <cernekee@...il.com>
Tested-by: Geert Uytterhoeven <geert+renesas@...der.be> (cpp/asm comparison)
As of commit 332fd7c4fef5f3b1 ("genirq: Generic chip: Change
irq_reg_{readl,writel} arguments") they cause build errors in
se7722_defconfig:
