platform/x86: acerhdf: clarify modinfo messages for BIOS override
Normally, a module parameter for a BIOS check override implies "pretend
you support this version" (and the user will enter their local version).
However, this driver uses the model/BIOS module parameters in a way that
is "pretend my system is the supported model XYZ with BIOS version ABC."
which is less common.
Since the help strings don't make such a distinction, one gets this
somewhat frustrating scenario, where the user sees the error, enters
*their* BIOS version and then gets the same error:
root@gw:~# modprobe acerhdf
acerhdf: Acer Aspire One Fan driver, v.0.7.0
acerhdf: unknown (unsupported) BIOS version Gateway /LT31 /v1.3307 , please report, aborting!
modprobe: ERROR: could not insert 'acerhdf': Invalid argument
root@gw:~# modprobe acerhdf force_bios=v1.3307
acerhdf: Acer Aspire One Fan driver, v.0.7.0
acerhdf: forcing BIOS version: v1.3307
acerhdf: unknown (unsupported) BIOS version Gateway /LT31 /v1.3307 , please report, aborting!
modprobe: ERROR: could not insert 'acerhdf': Invalid argument
Clarify the module param help text to make it clear that the driver
expects a choice from existing supported models/versions.
