    HID: wacom: more appropriate tool type categorization
    
    Recent eraser and pen tools are able to be distinguished
    by looking at its least significant nibble.
    This modification applies it to wacom_intuos_get_tool_type
    function and reduces its code lines.

I will write a bugreport in the coming days, do you have a name and email I could you to credit & CC you in the report? This then gets added in the form of "Reported-by: User Name <email@test.com>" when there is a fix found or the problematic commit is reverted. Also it would be good if you could be ready to supply more debug outputs once the Upstream developers ask for it.

Thank you very much. I couldn't have done it without your help and patience.

I have now sent out the report, lets see how it goes

(currently lore seems to be offline, but the link should work in a few hours)

gromit · 2024-10-14 14:42:51

The fix is now also on the way to the stable tree and to be released with 6.11.4 (most likely around wednesday): https://lore.kernel.org/all/20241014141 … dation.org
