[libcamera-devel] [PATCH 01/10] cam: options: Rename optional arg to prevent aliasing

[Kieran Bingham]

The parseValue function is given the optarg directly from the getopt
library, but the function retains the same name.

This causes an alias of the global optarg variable to be present in the
parseValue function. While this is not harmful, rename it to work
towards disabling aliases variables.
