From 6f3ef5c25cc762687a7341c18cbea5af54461407 Mon Sep 17 00:00:00 2001 From: Navid Emamdoost Date: Fri, 25 Oct 2019 23:53:30 -0500 Subject: [PATCH] wimax: i2400: Fix memory leak in i2400m_op_rfkill_sw_toggle In the implementation of i2400m_op_rfkill_sw_toggle() the allocated buffer for cmd should be released before returning. The documentation for i2400m_msg_to_dev() says when it returns the buffer can be reused. Meaning cmd should be released in either case. Move kfree(cmd) before return to be reached by all execution paths. Fixes: 2507e6ab7a9a ("wimax: i2400: fix memory leak") Signed-off-by: Navid Emamdoost Signed-off-by: David S.
