Bluetooth: btwilink: remove unnecessary static in bt_ti_probe()
Remove unnecessary static on local variable hst. Such variable is 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 the difference in the object file size. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 4029 2528 128 6685 1a1d drivers/bluetooth/btwilink.o after: text data bss dec hex filename 4007 2472 64 6543 198f drivers/bluetooth/btwilink.o Signed-off-by: Gustavo A.
