Subject: [PATCH] acerhdf: limit modalias matching to supported
BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958
The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models. This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T). This is not
fatal but worries users that see this message. Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.
