Describe the bug

As far as I understand this

zephyr/modules/lvgl/lvgl.c

Line 273 in 2bb7fcc

lv_log_register_print_cb(lvgl_log);

should be
after

zephyr/modules/lvgl/lvgl.c

Line 276 in 2bb7fcc

lv_init();

It is strange to initialize custom_log_print_cb and then clear this field inside lv_init using lv_memzero().
