Steven Rostedt (VMware) 561ca66910 tracing: Make -ENOMEM the default error for parse_synth_field() ... parse_synth_field() returns a pointer and requires that errors get surrounded by ERR_PTR(). The ret variable is initialized to zero, but should never be used as zero, and if it is, it could cause a false return code and produce a NULL pointer dereference. It makes no sense to set ret to zero. Set ret to -ENOMEM (the most common error case), and have any other errors set it to something else. This removes the need to initialize ret on *every* error branch.
