aes67-daemon/3rdparty/patches/ravenna-alsa-lkm-kernel-v5.patch
Andrea Bondavalli 5e223ddb53 Initial set of changes to to enable proper compilation ond operations on ARMv7 32bit platform.
- added patch to ALSA RAVENNA/AES67 Driver
- switched to CLANG compiler in order to compile the daemon succesfully
- disabled valgind memory check in daemon regression tests for ARM.
Demo and daemon regression test work properly.
Tests have been executed on the BeagleBone® Black board with ARM Cortex-A8 32-Bit and Ubuntu 18.04 distro
