Subject: [PATCH 5.15 37/80] XHCI: Separate PORT and CAPs macros into dedicated file
Date: Mon, 28 Oct 2024 07:25:17 +0100	[thread overview]
Message-ID: <20241028062253.654771723@linuxfoundation.org> (raw)
In-Reply-To: <20241028062252.611837461@linuxfoundation.org>

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Frank Li <Frank.Li@nxp.com>

[ Upstream commit c35ba0ac48355df1d11fcce85945f76c42d250ac ]

Split the PORT and CAPs macro definitions into a separate file to
facilitate sharing with other files without the need to include the entire
xhci.h.
