Date: Mon, 17 May 2021 16:02:56 +0200 Message-Id: <20210517140313.594670412@linuxfoundation.org> X-Mailer: git-send-email 2.31.1 In-Reply-To: <20210517140305.140529752@linuxfoundation.org> References: <20210517140305.140529752@linuxfoundation.org> User-Agent: quilt/0.66 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: stable@vger.kernel.org From: Sandeep Singh commit 3c128781d8da463761495aaf8898c9ecb4e71528 upstream. One of AMD xhci controller require reset on resume. Occasionally AMD xhci controller does not respond to Stop endpoint command. Once the issue happens controller goes into bad state and in that case controller needs to be reset.
