Subject: [net-next 04/15] net/mlx5e: Use correct return type
Date: Thu,  2 Sep 2021 12:05:43 -0700	[thread overview]
Message-ID: <20210902190554.211497-5-saeed@kernel.org> (raw)
In-Reply-To: <20210902190554.211497-1-saeed@kernel.org>

From: Roi Dayan <roid@nvidia.com>

modify_header_match_supported() should return type bool but
it returns the value returned by is_action_keys_supported()
which is type int.

is_action_keys_supported() always returns either -EOPNOTSUPP
or 0 and it shouldn't change as the purpose of the function
is checking for support. so just make the function return
a bool type.
