This patch removes an unreachable code found by the SVACE static analysis:
UNREACHABLE_CODE: This statement in the source code might be unreachable during program execution. [unreachable] unreachable at drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:787 retval != 0 is always false because at this program point the variable retval is always equal to 0 at drivers/gpu/drm/bridge/analogix/analogix_dp_core.c:786
