Subject: [PATCH] leds: Refactor st1202_led_set to use !! operator for boolean conversion

From: Pei Xiao <xiaopei01@...inos.cn>

cocci warnings:
    drivers/leds/leds-st1202.c:194:66-71: WARNING: conversion to bool not
needed here.

st1202_led_set function now uses the !! operator to convert the
enum led_brightness value to a boolean active state, which is then
passed to the st1202_channel_set function. This change maintains the
existing functionality.
