[PATCH 08/12] next-cube.c: move LED logic to new next_scr2_led_update()


From: Mark Cave-Ayland
Subject: [PATCH 08/12] next-cube.c: move LED logic to new next_scr2_led_update() function
Date: Fri, 15 Dec 2023 20:00:05 +0000

Ensure that the LED status is updated by calling next_scr2_led_update() whenever
the SC2 register is written.
