From 995dd0e82cc3b397fb0872949ffdad56a49ebf10 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 23 Jan 2015 17:08:21 +0100 Subject: tests: modetest: Accept connector names in addition to connector IDs Allow connector names to be used in the specification of the -s option. This requires storing the string passed on the command-line so that it can later be resolved to a connector ID (after the DRM device has been opened). Connector names are constructed from the connector type name and connector type ID using the same format as used internally in the Linux kernel.
