The patch causes the build to break when CONFIG_SENSORS_RASPBERRYPI_HWMON is turned on: error: implicit declaration of function 'disable_delayed_work_sync' The generic kernel has this config option turned off, so build tests for the noble upstream stable patchset didn't catch this issue after the patch applied cleanly to our tree. [Fix] Revert the patch in the generic noble kernel. [Test Plan] Build the kernel with CONFIG_SENSORS_RASPBERRYPI_HWMON turned on (or build noble:linux-aws). [Where problems could occur] Issues would be localized to the Raspberry Pi voltage monitor driver.
