There's no error. It's just an unnecessary line. It is still useful to find and fix such code fragments: your code will become a bit shorter.

This suspicious code was found in QT project by PVS-Studio static code analyzer.
Warning message is:
V501 There are identical sub-expressions to the left and to the right of the '&&' operator. QtWebKit renderstyle.h 162
