2.6.23 irda

about irda on 2.6.23, it seems to me there is a bit of code missing ...
i wander who and where is calling
"akita_set_ioexp(&akitaioexp_device.dev, AKITA_IOEXP_IR_ON);"

Okay, I'm not using akita, and 2.6.23 is very historic. Can you try on
recent kernel?

cause i need AKITA_IOEXP_IR_ON

on my 2.6.23 three i run the following script

my() {
echo "[*] $1"
echo "echo [*] $1 >> my-irda.log"
grep -r $1 $2 * >> my-irda.log
}

#echo > my-irda.log
my "irda_startup"
my "SPITZ_GPIO_IR_ON"
my "gpio_request(SPITZ_GPIO_IR_ON"
my "irda_shutdown"
my "irda_transceiver_mode"


and i get

could you point me into the right way ?
then i will write a kernel modul that will call
static void akita_irda_transceiver_mode(struct device *dev, int mode)
ot
akita_set_ioexp(&akitaioexp_device.dev, AKITA_IOEXP_IR_ON);

what "dev" needs ?


(i am not so skilled about kernel module)
