Initially I thought that this patch is a spam, but it is not. It is indeed
fixing a real bug in the driver. But the subject and description made it look
like a spam. Please follow the process defined in:
Documentation/process/5.Posting.rst to send the patches.
Essentially you need to properly describe what the patch does and how it impacts
the driver etc... Then there needs to be a valid 'Fixes' tag and stable list
should be CCed to backport to stable kernels.
