Subject: [Patch 1/1 v2] pata_via: HDD of VT6410/6415/6330 cannot be detected issue

When using VT6410/6415/6330 chips on some VIA's platforms, the HDD connects to VT6410/6415/6330 cannot be detected.
It is because the driver detects wrong via_isa_bridge ID, and then cause the this issue happen.
This patch will fix this problem.
