liquidio: lio_main: remove unnecessary static in setup_io_queues()
Remove unnecessary static on local variables cpu_id_modulus and cpu_id. Such variables are initialized before being used, on every execution path throughout the function. The static has no benefit and, removing it reduces the object file size. This issue was detected using Coccinelle and the following semantic patch: @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; In the following log you can see a significant difference in the object file size. Also, there is a significant difference in the bss segment. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 78689 15272 27808 121769 1dba9 drivers/net/ethernet/cavium/liquidio/lio_main.o after: text data bss dec hex filename 78667 15128 27680 121475 1da83 drivers/net/ethernet/cavium/liquidio/lio_main.o Signed-off-by: Gustavo A.
