Some checks failed
Build Kernel / Build all affected Kernels (push) Has been cancelled
When the reset button is next to the SFP cages, I2C operations on the
modules might cause interference on the button's GPIO line. Add a
debounce-interval of 5 times the poll-interval to ensure the line is
actually stable for some time and not just glitching.
This squashes commit 4357f32d41eb ("realtek: debounce reset key for
Zyxel GS1900") and commit 777c6106ed4e ("realtek: move debounce-interval
to correct node").
