Subject: can: fix memory leak in initial namespace support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a7bbd28f04ce4df26f07e96c4a743d529da99348;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

can: fix memory leak in initial namespace support

The can_rx_alldev_list is a per-net data structure now and allocated in
can_pernet_init(). Make sure the memory is free'd in can_pernet_exit() too.
