7.3-stable review patch. If anyone has any objections, please let me know. ------------------ From: Vishnu Reddy [ Upstream commit 1facae9bc3c1cfcabc77184754d64c349831cbc5 ] The bus_info field returned by VIDIOC_QUERYCAP used the abbreviated prefix "plat:" instead of the standard "platform:" prefix expected for platform devices. v4l2-compliance validates that bus_info for platform devices starts with "platform:", and fails otherwise: fail: ../utils/v4l2-compliance/v4l2-compliance.cpp(671): missing bus_info prefix ('plat:aa00000.video-codec:dec') Update the format string in iris_querycap() to use "platform:" so that v4l2-compliance bus_info check passes.
