Tom Zanussi 201fdd62bb tracing: Simplify assignment parsing for hist triggers ... [ Upstream commit b527b638fd63ba791dc90a0a6e9a3035b10df52b ] In the process of adding better error messages for sorting, I realized that strsep was being used incorrectly and some of the error paths I was expecting to be hit weren't and just fell through to the common invalid key error case. It also became obvious that for keyword assignments, it wasn't necessary to save the full assignment and reparse it later, and having a common empty-assignment check would also make more sense in terms of error processing. Change the code to fix these problems and simplify it for new error message changes in a subsequent patch.
