Subject: drm/amd/display: remove an unnecessary NULL check
Git-commit: cfafe238b585962089b8c7174315761f6b31e9d6
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

The "stream" pointer can't be NULL and it's dereferenced on the line
before so the check doesn't make sense.
