Subject: [PATCH] gpiolib: fix filtering out unwanted events

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.
