McClure" <zmc@...ian.net>, Alistair Buxton <a.j.buxton@...il.com>, Andrew Morton <akpm@...ux-foundation.org>, linux-omap@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] omap: define _toggle_gpio_edge_triggering only for OMAP1 The only usage of _toggle_gpio_edge_triggering is in an CONFIG_ARCH_OMAP1 is defined, too. This fixes a compiler warning: arch/arm/plat-omap/gpio.c:758: warning: '_toggle_gpio_edge_triggering' defined but not used when compiling for ARCH_OMAP2, ARCH_OMAP3 or ARCH_OMAP4.
