So I think this either needs to be reposted or get an ack from the maintainer (already CCed).

When copying data from skb, it needs to determine the copy length. It is easier to understand using min() here. Signed-off-by: Li Zetao <lizetao1@huawei.com> --- net/bluetooth/hidp/core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
