Today I retest HSW ULT, and I find the test results changed again.(Today I'm
using another disk, this is the only different with before). The result is much
more clearly now. If use -next-queued kernel, I can  reproduce the bug below:
"Bug 66294 - [HSW mobile] eDP fails to restore backlight". The other two
pipe(DP and HDMI) worked well.

If I use -nightly latest kernel, I find all pipe can worked very well, and
restored perfect.

Now, I think there's no need to report a new bug. I will checked the disk which
I used before.
