Re: [PATCH v8 1/6] platform/x86: intel_lpss: add resource conflict quirk for Dell Latitude 5285

[Andy Shevchenko]

Again, there is an in-thread new version, DO NOT DO this!
If you send a new version, start a *new* email thread.
With that, the v8 has no cover letter...

Note, using `b4` tool will help you in preparing patch series properly.
