From f94ca311d52de1ffc6632b67f48c0b711a4a4a0e Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Mon, 14 Jun 2021 13:23:41 +0200 Subject: [PATCH] media: ti-vpe: cal: fix queuing of the initial buffer [ 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.
