Sam Lantinga 2cbe9e2b77 Fixed bug 3322 - Missing error checking in testaudioinfo and testaudiohotplug
Simon Hug

The two tests test/testaudioinfo.c and test/testaudiohotplug.c are missing error checking when they call SDL_GetAudioDeviceName. This function can return NULL which the tests pass straight to SDL_Log.
