From dd3ea78fb82555132b60177fad2b92d1b339f6a2 Mon Sep 17 00:00:00 2001 From: Robert Foss Date: Wed, 13 Oct 2021 16:28:31 +0800 Subject: [PATCH] drm/bridge/sii8620: fix dependency on extcon stable inclusion from stable-5.10.50 commit 45415d1f99291d81ee945912d4e1d61c43cf0283 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=45415d1f99291d81ee945912d4e1d61c43cf0283 -------------------------------- [ Upstream commit 08319adbdde15ef7cee1970336f63461254baa2a ] The DRM_SIL_SII8620 kconfig has a weak `imply` dependency on EXTCON, which causes issues when sii8620 is built as a builtin and EXTCON is built as a module. The symptoms are 'undefined reference' errors caused by the symbols in EXTCON not being available to the sii8620 driver.
