Subject: [PATCH 1/4] backlight: lm3630a: Initialize backlight_properties on init
Date: Tue, 20 Feb 2024 00:11:19 +0100	[thread overview]
Message-ID: <20240220-lm3630a-fixups-v1-1-9ca62f7e4a33@z3ntu.xyz> (raw)
In-Reply-To: <20240220-lm3630a-fixups-v1-0-9ca62f7e4a33@z3ntu.xyz>

The backlight_properties struct should be initialized to zero before
using, otherwise there will be some random values in the struct.

Fixes: 0c2a665a648e ("backlight: add Backlight driver for lm3630 chip")
