From: Markus Elfring <elfr...@users.sourceforge.net> [ Upstream commit f6c8a317ab208aee223776327c06f23342492d54 ]
Source code review for a specific software refactoring showed the need for another correction because the error code "-1" was returned so far if a call of the function "sony_call_snc_handle" failed here. Thus assign the return value from these two function calls also to the variable "err" and provide it in case of a failure.
