Bug 130241 – Refactor checking log channel state in MediaPlayerPrivateGStreamerBase.

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Peter Molnar]

The channel is passed around only to check its state. Clean this up by adding a method to check whether a log channel is enabled.

Would be good to check the channel is not null.

I'm not quite sure about this style error. The exactly same change in this file passed a few days ago. Someone upgraded the stlye checker? :)
Should I fix the indentation in the whole file, even the lines not touched by this patch?

This is basically good but the logChannelEnabled local variable can easily be avoided, we like early returns in WebKit :)

This can be transformed to an early return: if (!channel) return false;

and then below return channel->state != WTFLogChannelOff;
So no need for a local variable

Thank you for the correction, it looks nicer indeed :)
