Subject: [PATCH v4 08/14] usb: ehci: initialize periodic_queue_dma
Date: Thu, 13 Aug 2026 17:26:28 +0200 [thread overview]
Message-ID: <20260813-rn102-rn104-series-v4-8-f932ac63efa0@gmail.com> (raw)
In-Reply-To: <20260813-rn102-rn104-series-v4-0-f932ac63efa0@gmail.com>
From: Luca Lauro <famlauro93l@gmail.com>
Store the DMA address of the periodic queue head in
ehci->periodic_queue_dma. Without this initialization the periodic
schedule may reference an invalid address.
