Adding new command line parameters for hardware quirks is generally
frowned upon these days and is usually greeted by Greg KH's trademark
"this isn't the 1990s anymore" comment.

Drivers are supposed to auto-detect hardware with quirks and handle
them correctly without the user having to add a command line option.

Users should not get accustomed to fiddling with the command line.
They won't have the need to report broken hardware and the driver
may never be amended to deal with affected models automatically.
