Subject: [PATCH v3 2/4] drm/simple_kms_helper: Add macro drmm_plain_simple_encoder_alloc()
Date:   Sun, 24 Jan 2021 08:55:50 +0000
Message-Id: <20210124085552.29146-3-paul@crapouillou.net>

This performs the same operation as drmm_simple_encoder_alloc(), but
only allocates and returns a struct drm_encoder instance.
