gpio_get_value() warning messages in dmesg...

Hello,

I'm using gpio kernel function calls in Linux (2.6.37) on a LogicPD eXperimenter board. I read the User DIP switch state with gpio_get_value on gpio pin #200,201 &207 and everyime my application do so, it generates a warning in the system log:

[  378.905761] WARNING: at drivers/gpio/gpiolib.c:1551 __gpio_get_value+0x30/0x5c()

BTW, I compiled the kernel to support GPIO debugging.

Anybody has seen this? It's annoying because all those traces slows the system down and make system log difficult to read. Should I worry about them?

Thanks,

Yves McDonald
