Subject: [PATCH 1/2] gmsl-yavta: Remove bash-isms
Date: Wed, 31 Jan 2018 23:01:08 +0200	[thread overview]
Message-ID: <20180131210108.28048-1-laurent.pinchart@ideasonboard.com> (raw)

The script contains two bash-specific constructs:

- Replace ${!var} expansion with eval
- Initialize conf1234 and conf5678 variables to avoid empty argument to
  -ne test
