From: "Leo (Sunpeng) Li" Date: Fri, 12 Jan 2018 13:13:11 -0500 Subject: drm/amd/display: Fix multiple definitions of handle_crc_irq Git-commit: fdb401d03d311399d844b9f23ec5ab98a2811f58 Patch-mainline: v4.17-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 If CONFIG_DEBUG_FS is disabled, then CRC should also be disabled. Therefore, amdgpu_dm_crtc_handle_crc_irq was redefined as a no-op function within amdgpu_dm.h. However, since amdgpu_dm.h is included in multiple files, this caused conflicts when linking during compile. Therefore, Use a macro to define the function as a no-op instead.
