ptp: Fix resource leak in case of error
A call to 'ida_simple_remove()' is missing in the error handling path. This as been spotted with the following coccinelle script which tries to detect missing 'ida_simple_remove()' call in error handling paths. /////////////// @@ expression x; identifier l; @@ * x = ida_simple_get(...); ... if (...) { ... } ... if (...) { ... goto l; } ... * l: ... when != ida_simple_remove(...); Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Acked-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.
