[9cxndy]

Summary

According to the kernel doc, left trigger should be ABS_HAT2Y not ABS_HAT2X.

Testing

• How was this tested? (e.g. Built and tested on specific devices, manual testing steps, URLs for CI/CD build artifacts.)
• Test results: (e.g. Screenshots, logs, performance metrics if applicable.)

Additional Context

• Add any other information that might be helpful for the reviewer (e.g., performance implications, potential risks, specific areas to focus on.)

already "corrected" by inputplumber profile,
do you have issues in games with triggers being flipped ?

[9cxndy]

but this kernel driver is objectively wrong... shouldn't require inputplumber to fix this when it can be fixed in the kernel.

[loki666]

no issues then

[spycat88]

I agree with @9cxndy this should be corrected if its wrong, it can wait until after stable.

[loki666]

then at the very least, the inputplumber mapping need to also be fixed

[loki666]

fix inputplumber mapping accordingly

[loki666]

and if we want be correct, we should even use ABS_Z/ABS_RZ
