Converting kzalloc to devm_kzalloc simplifies the code and ensures that the result, alert, is freed after the irq allocated by the subsequent devm_request_irq. This in turn ensures that when an interrupt can be triggered, the alert structure is still available. The problem of a free after a devm_request_irq was found using the following semantic match (http://coccinelle.lip6.fr/) // <smpl> @r exists@ expression e1,e2,x,a,b,c,d; identifier free; position p1,p2; @@ devm_request_irq@p1(e1,e2,...,x) ... when any when != e2 = a when != x = b if (...) { ... when != e2 = c when != x = d free@p2(...,x,...); ... return ...; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Jean Delvare <khali@linux-fr.org> |
