Subject: [PATCH v10 02/12] pwm: mediatek: droping the check for of_device_get_match_data
Date: Wed, 25 Sep 2019 22:32:27 +0800 [thread overview]
Message-ID: <1569421957-20765-3-git-send-email-sam.shih@mediatek.com> (raw)
In-Reply-To: <1569421957-20765-1-git-send-email-sam.shih@mediatek.com>
This patch drop the check for of_device_get_match_data.
Due to the only way call driver probe is compatible match.
The .data pointer which point to the SoC specify data is
directly set by driver, and it should not be NULL in our case.
We can safety remove the check for of_device_get_match_data.
