Subject: [PATCH 4/4] HID: do not inline some hid_hw_ functions
Date: Thu,  2 Dec 2021 10:53:34 +0100	[thread overview]
Message-ID: <20211202095334.14399-5-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <20211202095334.14399-1-benjamin.tissoires@redhat.com>

We don't gain much by having them as inline, and it
actually prevents us to attach a probe to those helpers.
