In case of error, the function rxrpc_get_transport returns an ERR pointer, but never returns a NULL pointer. So after a call to this function, a NULL test should be replaced by an IS_ERR test. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @correct_null_test@ expression x,E; statement S1, S2; @@ x = rxrpc_get_transport(...) <... when != x = E if ( ( - x@p2 != NULL + ! IS_ERR ( x ) | - x@p2 == NULL + IS_ERR( x ) ) ) S1 else S2 ...> ? x = E; // </smpl> Signed-off-by: Julien Brunel <brunel@diku.dk> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.
