In the upstream kernel and vivid kernel, these two patches introduce a
regression, after applied these two patches, the headset jack will not
detect plug and unplug anymore. So we need one more patch (831bfdf9)
to fix this regression in the upstream kernel or in the vivid kernel.

But in the utopic kernel, these two patches will not introduce the
regression since headset jack detection fixing patch has not been
in the utopic yet and it is not easy to backport headset jack
detection fixing patches to utopic since the patches depend on
the macro UPDATE_COEF(), to introduce UPDATE_COEF() in the utopic
kernel, the patch_realtek.c will be greatly changed.

As a result, I just send these two patches to fix noise problem.

Also please refer to upstream bug for these 2 patches:
Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=99851
