Hi Christian,

Thanks already for volunteering to test this!

Hello Sven,

Damien (Hypex) has successfully tested the RC3 of kernel 5.15 with your
modified i2c driver on his Nemo board yesterday. [1]

Thanks a lot, that's great to hear!
If he wants to I can credit him with a Tested-by tag in the commit message,
see e.g. https://www.kernel.org/doc/html/latest/process/submitting-patches.html#using-reported-by-tested-by-reviewed-by-suggested-by-and-fixes.


Best,


Sven
