Subject: [PATCH v2 6/7] media: mtk-vcodec: don't check return val of mtk_venc_get_q_data
Date: Wed, 17 Nov 2021 15:06:34 +0200 [thread overview]
Message-ID: <20211117130635.11633-7-dafna.hirschfeld@collabora.com> (raw)
In-Reply-To: <20211117130635.11633-1-dafna.hirschfeld@collabora.com>
The function mtk_venc_get_q_data always returns a reference
so there is no need to check if the return value is null.
In addition move the q_data initialization to the declaration
