From 0d82c41ac1a0a68e91b75dffba5a622d10f9aa3e Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Thu, 30 Apr 2020 06:11:37 -0700 Subject: [PATCH] uds: Convey transmit path errors to the caller. The transport layer's functional interface foresees having error codes percolate back up to the caller. However, up until now, the uds module simply returned -1 for any error. This patch lets the code return the specific error instead. In addition, it removes the gratuitous printing of the error message, leaving that task up to caller, just like the other transport modules.
