staging: Use available error codes (4d9db977) · Commits · 戴 / test

An error code is stored in a variable, but 0 is returned instead. Use the variable instead of 0. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/ ) // <smpl> @r@ local idexpression x; constant C; @@ if (...) { ... x = -C ... when != x ( return <+...x...+>; | return NULL; | return; | * return ...; ) } // </smpl> Signed-off-by:
