Subject: [PATCH v2 00/12] Remove redundant checks on existence of 'bridge->encoder'
Date: Mon, 13 May 2024 23:30:57 +0800 [thread overview]
Message-ID: <20240513153109.46786-1-sui.jingfeng@linux.dev> (raw)
The checks on the existence of bridge->encoder in the implementation of
drm_bridge_funcs::attach() is not necessary, as it has already been checked
in the drm_bridge_attach() function call by previous bridge or KMS driver.
The drm_bridge_attach() will quit with a negative error code returned if
it fails for some reasons, hence, it is guaranteed that the .encoder member
of the drm_bridge instance is not NULL when various bridge attach functions
are called.
V1 -> V2:
* Gather all similar patches to form a series (Laurent)
* Fix various spell error (Laurent)
* Correct commit message for bridges of i.MX (Ying)
