commit 38f64f650dc0e44c146ff88d15a7339efa325918 upstream.
bt_skb_sendmsg helps takes care of allocation the skb and copying the
the contents of msg over to the skb while checking for possible errors
so it should be safe to call it without holding lock_sock.

Bluetooth: Add bt_skb_sendmsg helper
commit 38f64f650dc0e44c146ff88d15a7339efa325918 upstream.
bt_skb_sendmsg helps takes care of allocation the skb and copying the
the contents of msg over to the skb while checking for possible errors
so it should be safe to call it without holding lock_sock.

Bluetooth: Fix bt_skb_sendmmsg not allocating partial chunks
commit 29fb608396d6a62c1b85acc421ad7a4399085b9f upstream.
Since bt_skb_sendmmsg can be used with the likes of SOCK_STREAM it
shall return the partial chunks it could allocate instead of freeing
everything as otherwise it can cause problems like bellow.

Bluetooth: Fix passing NULL to PTR_ERR
commit 266191aa8d14b84958aaeb5e96ee4e97839e3d87 upstream.
Passing NULL to PTR_ERR will result in 0 (success), also since the likes of
bt_skb_sendmsg does never return NULL it is safe to replace the instances of
IS_ERR_OR_NULL with IS_ERR when checking its return.

Bluetooth: Add bt_skb_sendmmsg helper
commit 97e4e80299844bb5f6ce5a7540742ffbffae3d97 upstream.
This works similarly to bt_skb_sendmsg but can split the msg into
multiple skb fragments which is useful for stream sockets.
