Subject: [PATCH] backlight: ktd2801: fix LED dependency
Date: Mon, 12 Feb 2024 12:18:12 +0100	[thread overview]
Message-ID: <20240212111819.936815-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

The new backlight driver unconditionally selects LEDS_EXPRESSWIRE, which
is in a different subsystem that may be disabled here:

WARNING: unmet direct dependencies detected for LEDS_EXPRESSWIRE
  Depends on [n]: NEW_LEDS [=n] && GPIOLIB [=y]
  Selected by [y]:
  - BACKLIGHT_KTD2801 [=y] && HAS_IOMEM [=y] && BACKLIGHT_CLASS_DEVICE [=y]

Change the select to depends, to ensure the indirect dependency is
met as well even when LED support is disabled.

Fixes: 66c76c1cd984 ("backlight: Add Kinetic KTD2801 backlight support")
