Subject: [PATCH v4 11/13] drm/msm/dpu: use drmm-managed allocation for dpu_encoder_phys
Date: Sat, 2 Dec 2023 00:18:43 +0300 [thread overview]
Message-ID: <20231201211845.1026967-12-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20231201211845.1026967-1-dmitry.baryshkov@linaro.org>
Change struct allocation of encoder's phys backend data to use
drmm_kzalloc(). This removes the need to perform any actions on encoder
destruction.
