X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=910d6c320cac65c81d66e8fd30dca167092722eb;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [GENETLINK]: Relax dances with genl_lock. The genl_unregister_family() calls the genl_unregister_mc_groups(), which takes and releases the genl_lock and then locks and releases this lock itself. Relax this behavior, all the more so the genl_unregister_mc_groups() is called from genl_unregister_family() only. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
