drivers/staging: Remove useless return variables
This patch remove variables that are initialized with a constant, are never updated, and are only used as parameter of return. Return the constant instead of using a variable. Verified by compilation only. The coccinelle script that find and fixes this issue is: // <smpl> @@ type T; constant C; identifier ret; @@ - T ret = C; ... when != ret when strict return - ret + C ; // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
