[PATCH] chcr: remove unused variables net_device, pi, adap and cntrl

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variables adap, pi and cntrl are assigned but are never read, hence
they are redundant and can be removed.

Cleans up various clang build warnings.
