[PATCH 0/6] platform/x86: acerhdf: new BIOS string, better modparam handling

[Paul Gortmaker]

I came across this older netbook over the xmas holidays, and noticed the
acerhdf driver wouldn't load.  Turns out the BIOS string was too new,
and not listed in the driver.  There were module params for overrides,
but I found their use isn't quite clear without reading the source.

Here I clarify some of the module parameter usage, and then add the new
BIOS string, so they won't be needed for this particular platform.  Some
probe code is also shifted out to be __init to reduce the driver size a
bit.  Further details can be found in the respective commit logs.

Since it was months ago when I created these patches, I retested on top
of tree to ensure things still work, as can be seen below.
