+Subject: [PATCH] [clang 11] fix build errors due to -WWc++11-narrowing
+ https://bugs.webkit.org/show_bug.cgi?id=211193
+
+Reviewed by Adrian Perez de Castro.
+
+Fixes the following errors,
+
+Source/WebCore/html/MediaElementSession.cpp:1059:9: error: type 'WebCore::RenderMedia *' cannot be narrowed to 'bool' in initializer list [-Wc++11-narrowing]
+m_element.renderer(),
+^~~~~~~~~~~~~~~~~~~~
+
+Source/WebCore/style/StyleResolver.cpp:106:55: error: type 'const char [4]' cannot be narrowed to 'bool' in initializer list [-Wc++11-narrowing]
+m_mediaQueryEvaluator = MediaQueryEvaluator { "all" };
+                                              ^~~~~
+Source/WebCore/style/StyleResolver.cpp:106:55: note: insert an explicit cast to silence this issue
+m_mediaQueryEvaluator = MediaQueryEvaluator { "all" };
+                                              ^~~~~
+                                              static_cast<bool>( )
+
+* html/HTMLMediaElement.h:
+(WebCore::HTMLMediaElement::hasRenderer const):
+MediaElementSession was implicitly casting a pointer to a bool,
+which is not allowed with modern Clang checks. Add a helper method
+to encapsulate the now required static_cast<bool>.
+* html/MediaElementSession.cpp: Use the new helper method to see
+if the HTMLMediaElement has an associated renderer.
+(WebCore::MediaElementSession::updateMediaUsageIfChanged):
+* style/StyleResolver.cpp: This was calling MediaQueryEvaluator {
+"all" }; and seemingly expecting to cast a const char[] to a bool,
+or maybe String? It's confusing because of the MediaQueryEvaluator
+API. If it was implicitly converting to bool then that could be
+unintentional. Such casts are not allowed either now. The
+MediaQueryEvaluator's default constructor says it returns true for
+"all", which appears to be the original intent of this call, so I
+replaced it with that.
+(WebCore::Style::Resolver::Resolver):
