For every chip for which the bus notifier triggers, the quirk code performs I2C transfer on that I2C bus for all addresses in the list. The problem is that this may generate transfers to non-existing chips on systems with multiple I2C busses. This patch adds a check to verify that the I2C bus to which the chip with shared IRQ is attached to matches the I2C bus of the chip which triggered the bus notifier and only starts the I2C transfer if they match.

Thanks, Sorry for missing that, I think that the bugfix should have had the following. Let me know if/how you want to handle updating the patch's changelog.

I've added it to Cc here, but I don't know if that's sufficient. If you'd rather have me pick up the patch for 5.0 as well, I can also do that and add the Cc/Fixes lines there. We will then have a duplicate commit in 5.1, but it should not cause any merge issues. Arnd ^ permalink raw reply [flat|nested] 9+ messages in thread

Ok, sounds good. To clarify: I think you should only write them /after/ the commit is in mainline then, i.e. near the end of the 5.1 merge window.
