xen: Use ERRP_GUARD() (2020-07-10 15:18:09 +0200)
----------------------------------------------------------------
Error reporting patches patches for 2020-07-07
* Improve documentation
* Codify rules for less clumsy error handling
* Convert a substantial amount of code to adhere to them
* ERRP_GUARD() infrastructure to avoid more clumsiness
* First batch of conversions to it
----------------------------------------------------------------
