Change a static function's comment from "/**" (indicating kernel-doc notation) to "/*" (indicating a regular C language comment). This prevents multiple kernel-doc warnings: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:4343: warning: Function parameter or member 'max_supported_frl_bw_in_kbps' not described in 'intersect_frl_link_bw_support' drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:4343: warning: Function parameter or member 'hdmi_encoded_link_bw' not described in 'intersect_frl_link_bw_support' drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link_dp.c:4343: warning: expecting prototype for Return PCON's post FRL link training supported BW if its non().

The pointer reg is being assigned a value that is not read, the exit path via label 'out' never accesses it. The assignment is redundant and can be removed.

In amdgpu_dm_connector_add_common_modes(), amdgpu_dm_create_common_mode() is assigned to mode and is passed to drm_mode_probed_add() directly after that. drm_mode_probed_add() passes &mode->head to list_add_tail(), and there is a dereference of it in list_add_tail() without recoveries, which could lead to NULL pointer dereference on failure of amdgpu_dm_create_common_mode(). Fix this by adding a NULL check of mode. This bug was found by a static analyzer. Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.

[why] There is a change previously to disallow DM to set dp drive setings when stream is not present. The logic might not work well with DP PHY complaince scenario with a PHY test fixture attachment. We need to make the method allow DP link drive settings changes even without stream attached to it. [how] revert back to previous code in set drive setting function then add an empty link_resource structure, then assign link resource based on current link resource if link resource is allocated to the current pipe.

[Why] If the DPCD caps specifies a PSR version newer than PSR_VERSION_1 then we fallback to using PSR_VERSION_1 in amdgpu_dm_set_psr_caps. This gets overriden with the raw DPCD value in amdgpu_dm_link_setup_psr, which can result in DMCUB hanging if we pass in an unsupported PSR version number. [How] Fix the hang by using link->psr_settings.psr_version directly during amdgpu_dm_link_setup_psr. Tested-by:

[Why] Currently, when we're tentatively detecting link configuration under mst case, we will wrongly notify a none existing stream sink to drm layer. It's due to we'll call amdgpu_dm_update_connector_after_detect() within dm_helpers_read_local_edid() to update connector when we're still under tentative detection procedure. [How] dm_helpers_read_local_edid() was designed to do "read" only. Don't update drm connector status when we're still under detection process. Tested-by:
