From 613f21505b25a4f43f33de00f11afc059bedde2b Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 4 Jul 2024 11:01:51 +0200 Subject: media: cec: core: add new CEC_MSG_FL_REPLY_VENDOR_ID flag If this flag is set, then the reply is expected to consist of the CEC_MSG_VENDOR_COMMAND_WITH_ID opcode followed by the Vendor ID (as used in bytes 1-4 of the message), followed by the struct cec_msg reply field. Note that this assumes that the byte after the Vendor ID is a vendor-specific opcode. This flag makes it easier to wait for replies to vendor commands, using the same CEC framework support for waiting for regular replies. Support for this flag is indicated by setting the new CEC_CAP_REPLY_VENDOR_ID capability.
