From 8761a39e3f9d9f41a593af2fce1ba41537c35b83 Mon Sep 17 00:00:00 2001 From: Sui Jingfeng Date: Mon, 13 May 2024 23:31:02 +0800 Subject: [PATCH] drm/bridge: it6505: Remove a redundant check on existence of bridge->encoder In it6505_bridge_attach(), the check on the existence of 'bridge->encoder' is not necessary, as it has already been checked in the drm_bridge_attach() which happens prior to it6505_bridge_attach() get called. Note that the it6505_bridge_attach() will only be called by .attach() of the previous bridge or KMS driver. The previous 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 it6505_bridge_attach() function get called. Remove the redundant checking codes "if (!bridge->encoder) { ... }".
