Hi Morimoto-san,

I am seeing the following, is it expected?

gpio-keys gpio-keys: Unable to get irq number for GPIO 99, error -38
gpio-keys: probe of gpio-keys failed with error -38

Hi Simon

Thank you for checking patch.

Sorry for confusion.
Yes. gpio-keys support needs +1 patch.

I expected it on [0/6] mail :)

------------------------------------------
#5 patch require R8A7740 .gipo_irq support patch which I posted this morning.
[PATCH] ARM: mach-shmobile: pfc-r8a7740: add .gpio_irq support
------------------------------------------

Best regards

Sorry, I should have read that email more thoroughly.
