[PATCH] hid: Kconfig: Add LEDS_CLASS_MULTICOLOR dependency to HID_LOGITECH

From: Kate Hsuan
Date: Tue Feb 11 2025 - 00:03:15 EST


The test bot found an issue with building hid-lg-g15.

All errors (new ones prefixed by >>):

powerpc-linux-ld: drivers/hid/hid-lg-g15.o: in function `lg_g510_kbd_led_write':
>> drivers/hid/hid-lg-g15.c:241:(.text+0x768): undefined reference to `led_mc_calc_color_components'
powerpc-linux-ld: drivers/hid/hid-lg-g15.o: in function `lg_g15_register_led':
>> drivers/hid/hid-lg-g15.c:686:(.text+0xa9c): undefined reference to `devm_led_classdev_multicolor_register_ext'

Since multicolor LED APIs manage the keyboard backlight settings of
hid-lg-g15, the LEDS_CLASS_MULTICOLOR dependency was added to
HID_LOGITECH.
