following controls:\n- ColourGains\n- ColourCorrectionMatrix\n- FrameDurationLimits\n\nA mismatch of scalarness in these fields causes deserialization errors\nin ControlSerializer which manifest when IPAs are run in isolation.\n\nFix the scalarness of these controls where relevant.\n\nSigned-off-by: Paul Elder \n---\nNo change in v3\n\nNo change in v2\n---\n src/ipa/ipu3/ipu3.cpp | 4 +++-\n
