[PATCH] drm: bridge: DRM_SIL_SII8620 should depend on, not select INPUT

From: Randy Dunlap
Date: Sun Jun 30 2019 - 23:39:36 EST


From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

A single driver should not enable (select) an entire subsystem,
such as INPUT, so change the 'select' to "depends on".

Fixes: d6abe6df706c ("drm/bridge: sil_sii8620: do not have a dependency of RC_CORE")

Linus has written this a couple of times in the last 15 years or so,
but my search fu cannot find it. And there are a few drivers in the
kernel tree that do this, but we shouldn't be adding more that do so.
