Hi all,

Just inform you a news reported by a user who confirmed the wake up
issue can't be reproduce by the new kernel.
https://bugzilla.kernel.org/show_bug.cgi?id=61651#c126

I am using this patch for a long time. I was experiencing the "wake up
twice" bug, but with recent kernel version, I don't have this issue
anymore.
I can't tell which version actually fix the bug (I don't remember..).
