lib(p)ata SMART support?

lib(p)ata SMART support?

Using legacy drivers I can use any SMART tools out there; HDD does support 
SMART. Running libata + pata_ali, smartctl claims device does not support 
SMART. This is sort of regression when switching from legacy drivers.

Try smartctl -d ata.

Right, it works. thank you. I wonder if it possible to automatically find the 
correct device type?

The current implementation guesses the device type by device name,
which apparently doesn't work with libata. I don't know if there's a
better way to figure out.

If you are using smartmontools, you need to pass "-d ata" to the tools.
