[PATCH] gpiolib: fix filtering out unwanted events

[Bartosz Golaszewski]

Hi Linux,

I've just fixed an issue in libgpiod which accidentally also led to
filtering out unwanted events in user space instead of gpiolib kernel
code. I then noticed that programs don't behave correctly and tracked
it down to an issue in gpiolib.c.

Please take a look at the fix. The bug has been there for some time and
it's quite late in the release cycle, but I believe it should still go
in v4.12 since currently the character device interface doesn't do what
it promises to.
