Subject: [PATCH 10/17] i3c: mipi-i3c-hci: Move DMA suspend/resume callbacks
Date: Mon, 14 Sep 2026 14:29:56 +0300	[thread overview]
Message-ID: <20260914113003.183150-11-adrian.hunter@intel.com> (raw)
In-Reply-To: <20260914113003.183150-1-adrian.hunter@intel.com>

Relocate hci_dma_suspend() and hci_dma_resume() closer to the DMA IO
operations table in preparation for upcoming changes.

No functional change.
