Subject: libcamera: Declare static local variables as const where applicable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We use static local variables to indicate errors in methods that return
a const reference. The local variables can thus be const, make them so.
