Subject: [PATCH v2] drm/bridge/sii8620: fix dependency on extcon
Date: Thu, 8 Apr 2021 15:07:46 +0200 [thread overview]
Message-ID: <20210408130746.175358-1-robert.foss@linaro.org> (raw)
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.
