The Apple M3 machines, and potentially M1/M2 machines with updated SMC firmware generate a new set of SMC events starting with 0x7113 when cables are plugged or unplugged. Without this patch, the kernel logs "Unknown charger event" errors, and the power status may not update immediately. The event structure is 0x7113[Port][Status]. Observed on M3: - Port 0 (USB-C): 0x711300xx - Port 1 (USB-C): 0x711301xx - Port 2 (MagSafe): 0x711302xx - Disconnect: 0x7113ffxx Status 0x04 indicates a stable connection, while 0x02/0x03 appear during negotiation. This patch handles these events and triggers a power_supply_changed notification. Signed-off-by: Michael Reeves <michael.reeves077@gmail.com>
