Hi Linus-san

Thanks for your reply!

I have just verified this on v4.7-rc5, this issue still happens.
But we find out that the issue had already happened before your 
following patch was released.
"ff2b1359 gpio: make the gpiochip a real device" (the patch that you 
have created before)
I mean, your patch helped us to find out the issue.

To Geert-san.

I'd like to divide Unbind-Rebind test  into two cases of Normal Test and 
Abnormal Test.

First, If we try to unbind/rebind the gpio device(ex: key, hdmi..) then 
unbind/rebind the gpio-rcar,
It works normally without error message. This test case is normal test.
Refer to (GPIO_Unbind-Rebind_Abnormal-Test_log.txt)

But on the other hand, If we try to unbind/rebind the gpio-rcar without 
unbinding/rebinding gpio device,
The warning message looks like from kernel will happens. This test case 
is abnormal test.
(Refer to GPIO_Unbind-Rebind_Normal-Test_logs.txt)

In abnormal Test case, an error message occurs definitely from the 
driver or the core class of the driver.
But I think we should consider the error or warning message looks like a 
kernel warning message.

Thank you!
Jinso/Hiep.
