From 650cede0415bad26f487c25e8eb3b39bfe04e740 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Thu, 28 Mar 2024 09:03:20 -0700 Subject: [PATCH] usb: typec: ptn36502: Only select DRM_AUX_BRIDGE with OF CONFIG_DRM_AUX_BRIDGE depends on CONFIG_OF but that dependency is not included when CONFIG_TYPEC_MUX_PTN36502 selects it, resulting in a Kconfig warning when CONFIG_OF is disabled: WARNING: unmet direct dependencies detected for DRM_AUX_BRIDGE Depends on [n]: HAS_IOMEM [=y] && DRM_BRIDGE [=y] && OF [=n] Selected by [m]: - TYPEC_MUX_PTN36502 [=m] && USB_SUPPORT [=y] && TYPEC [=m] && I2C [=y] && (DRM [=y] || DRM [=y]=n) && DRM_BRIDGE [=y] Only select CONFIG_DRM_AUX_BRIDGE when CONFIG_DRM_BRIDGE and CONFIG_OF are enabled to clear up the warning. This results in no functional change because prior to the refactoring that introduces this warning, ptn36502_register_bridge() returned 0 when CONFIG_OF was disabled, which continues to occur with drm_aux_bridge_register() when CONFIG_DRM_AUX_BRIDGE is not enabled.
