Subject: [PATCH 06/16] i3c: mipi-i3c-hci: Call hci_dma_xfer_done() from dequeue path
Date: Thu, 16 Apr 2026 20:56:54 +0300	[thread overview]
Message-ID: <20260416175704.41217-7-adrian.hunter@intel.com> (raw)
In-Reply-To: <20260416175704.41217-1-adrian.hunter@intel.com>

hci_dma_dequeue_xfer() relies on state normally updated by the DMA
interrupt handler.  Ensure that state is current by explicitly invoking
hci_dma_xfer_done() from the dequeue path.

This handles cases where the interrupt handler has not (yet) run.
