[PATCH 2/4] net/idpf: re-enable unused variable warnings

[Bruce Richardson]

The idpf driver was being built with warnings disabled for unused
variables. However, while the warning was being disabled in the base
code directory, all suppressed warnings were in the main directory.
Therefore, just remove the unused variables and re-enable the
warnings.
