From a6ca2e10f795111a90a4efabb07717258669e03d Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 26 Jan 2013 21:38:35 +0100 Subject: ssb: add gpio_to_irq The old bcm47xx gpio code had support for gpio_to_irq, but the new code did not provide this function, but returned -ENXIO all the time. This patch adds the missing function. arch/mips/bcm47xx/wgt634u.c calls gpio_to_irq() and got the correct irq number with the old gpio handling code. With this patch the code in wgt634u.c should work again. I do not have a wgt634u to test this. Signed-off-by: Hauke Mehrtens Signed-off-by: John W.
