[PATCH v2 2/2] drm/i915/hdcp: Fix uninitialized symbol

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Move (num_hdcp_streams > 0) condition to stream_encryption()
code block, where it actually belongs.
This fixes the static analysis error of uninitialized symbol 'ret'.
