genetlink: Fix uninitialized variable in genl_validate_assign_mc_groups()
net/netlink/genetlink.c: In function ‘genl_validate_assign_mc_groups’: net/netlink/genetlink.c:217: warning: ‘err’ may be used uninitialized in this function Commit 2a94fe48f32ccf7321450a2cc07f2b724a444e5b ("genetlink: make multicast groups const, prevent abuse") split genl_register_mc_group() in multiple functions, but dropped the initialization of err. Initialize err to zero to fix this. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: David S. Miller <davem@davemloft.net>
