From a57e191ebbaa0363dbf352cc37447c2230573e29 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 5 Apr 2024 16:35:10 +0200 Subject: [PATCH] drm: fix DRM_DISPLAY_DP_HELPER dependencies, part 2 After my fix yesterday, I ran into another problem of the same kind: aarch64-linux-ld: drivers/gpu/drm/bridge/analogix/analogix_dp_core.o: in function `drm_dp_dpcd_readb': analogix_dp_core.c:(.text+0x194): undefined reference to `drm_dp_dpcd_read' aarch64-linux-ld: drivers/gpu/drm/bridge/analogix/analogix_dp_core.o: in function `drm_dp_dpcd_writeb': analogix_dp_core.c:(.text+0x214): undefined reference to `drm_dp_dpcd_write' aarch64-linux-ld: drivers/gpu/drm/bridge/analogix/analogix_dp_core.o: in function `analogix_dp_stop_crc': analogix_dp_core.c:(.text+0x4b0): undefined reference to `drm_dp_stop_crc' aarch64-linux-ld: drivers/gpu/drm/bridge/analogix/analogix_dp_core.o: in function `analogix_dp_start_crc': analogix_dp_core.c:(.text+0xbe8): undefined reference to `drm_dp_start_crc' Add the same dependency again to ROCKCHIP_ANALOGIX_DP after checking that nothing else selects the analogix driver. Also add a dependency to DRM_ANALOGIX_DP to make it easier to identifier future problems of this type when they get introduced.
