PVS-Studio warning V501 for Skia

bool isDisabled() const {
  return kKeep_StencilOp == fFrontPassOp   &&
         kKeep_StencilOp == fBackPassOp    &&
         kKeep_StencilOp == fFrontFailOp   &&
         kKeep_StencilOp == fFrontFailOp   &&
         kAlways_StencilFunc == fFrontFunc &&
         kAlways_StencilFunc == fBackFunc;
}

Here we seem to have several errors at once. Besides the repeating condition, && and || may be mixed up.

This suspicious code was found in Skia project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions 'kKeep_StencilOp == fFrontFailOp' to the left and to the right of the '&&' operator. skia grstencil.h 159
