macsec: add noinline tag to avoid a frame size warning
seen with debug config: drivers/net/macsec.c: In function 'dump_secy': drivers/net/macsec.c:2597: warning: the frame size of 2216 bytes is larger than 2048 bytes [-Wframe-larger-than=] just mark it with noinline_for_stack, this is netlink dump code. v2: use 'static noinline_for_stack int' consistently Cc: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Florian Westphal <fw@strlen.de> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.
