[alsa-devel] [PATCH v2] ALSA: hda - Add two more machines to the power_save_blacklist

[Hui Wang]

Recently we set CONFIG_SND_HDA_POWER_SAVE_DEFAULT to 1 when
configuring the kernel, then two machines were reported to have noise
after installing the new kernel. Put them in the blacklist, the
noise disappears.

In the V2, put the Intel entry in the blacklist according to pciid's
order, and change the machine name "Intel Laptop 8086:2064" to
"Intel SDP 8086:2064".
