This was reported by the 'kernel test robot' after my change in v1. - Also set the 'max_brightness' to 'blink_brightness' if no 'blink_brightness' was set. This fixes a problem at startup when the brightness is still set to 0 and only 'line_*' is evaluated. I looked in the netdev trigger and that's exactly how it's done there. v1: This is a follow-up patchset, based on the mailing list discussion from March 2023 based on the old patchset v7 [1]. I have changed, the LED trigger handling via the sysfs interfaces as suggested by Uwe Kleine-König.
