Subject: [PATCH 2/6] media: imon_raw: refactor endpoint lookup
Date: Mon, 30 Mar 2026 12:11:37 +0200	[thread overview]
Message-ID: <20260330101141.1664143-3-johan@kernel.org> (raw)
In-Reply-To: <20260330101141.1664143-1-johan@kernel.org>

Use the common USB helper for looking up interrupt-in endpoints instead
of open coding.
