From a9a9cbf081414de0261279e3b11ada2f0a7f7e83 Mon Sep 17 00:00:00 2001 From: Pan Xiuli Date: Wed, 15 Apr 2020 15:28:06 -0500 Subject: ASoC: SOF: make sof_ipc_cc_version to fixed length Align struct sof_ipc_cc_version to firmware definition in SOF ABI 3.15.0. The struct definition was changed due to errors in FW build. The Cadence XCC compiler produces incorrect linkage section sizes, when a variable length array is used in the compiler version struct. The firmware definition was changed to a fixed 32 byte compiler description string. This length covers all released firmware binaries and thus only a minor ABI change is needed. As the same structure is used in IPC messages between driver and firmware, the kernel needs to be aligned to firmware change.
