Subject: libcamera: camera: Fix std::ostringstream initialisation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We use the std::ostringstream class to generate log messages in the
Camera class. The stream is initialised with initial content, but is not
opened without seeking to the end, which results in the content being
overwritten immediately. Fix it by opening the stream with
std::ios_base::ate.
