Subject: [PATCH] omap: define _toggle_gpio_edge_triggering only for OMAP1
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The only usage of _toggle_gpio_edge_triggering is in
an #ifdef CONFIG_ARCH_OMAP1 block, so only provide it if
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.
