v4l: Export enums used by tracepoints to user space

2015-04-08T14:58:25Z

Enums used by tracepoints for __print_symbolic() are shown in the tracepoint format files with just their names and not their values. This makes it difficult for user space tools to know how to convert the binary data into their string representations. By adding the use of TRACE_DEFINE_ENUM(), the enum names will be mapped to their values and shown in the tracing file system to let tools convert the data as necessary.
