Subject: drm/i915/display: Return early after MISSING_CASE for write_dp_sdp
Git-commit: d121f63c00e3b82f2e72b1db0de3e233c2ba2126
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Avoid using the uninitialised len along the impossible error path to
shut the compiler up:
drivers/gpu/drm/i915/display/intel_dp.c:4928 intel_write_dp_sdp() error: uninitialized symbol 'len'.
