Crash under VTIsHardwareDecodeSupported
https://bugs.webkit.org/show_bug.cgi?id=299949
rdar://157511010
Reviewed by Youenn Fablet.
We are receiving reports about crashes under VTIsHardwareDecodeSupported. The
reports indicate that the crashes are
due to leaks related to IOKit connections. VTIsHardwareDecodeSupported is being
called in response to the
UpdateGPUProcessPreferences message, and it's possible that this message is
being sent many times. This patch
speculatively addresses the issue by calling VTIsHardwareDecodeSupported only
once, which should be sufficient.
