[PATCH AUTOSEL 5.13 010/219] media: ti-vpe: cal: fix queuing of the initial buffer

[Sasha Levin <sashal@kernel.org>]

From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>

[ Upstream commit 892c37f8a3d673b945e951a8754695c119a2b1b0 ]

When starting streaming the driver currently programs the buffer
address to the CAL base-address register and assigns the buffer pointer
to ctx->dma.pending. This is not correct, as the buffer is not
"pending", but active, and causes the first buffer to be needlessly
written twice.

Fix this by assigning the buffer pointer to ctx->dma.active.
