From: Jacopo Mondi Date: Mon, 4 May 2026 12:43:14 +0000 (+0200) Subject: media: rcar-vin: Drop min_queued_buffers X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=a947fc3ba8a0c097862613bbaaa0bbd06d10b0d2;p=thirdparty%2Flinux.git media: rcar-vin: Drop min_queued_buffers The R-Car VIN driver already uses a scratch buffer to sustain capture operations in absence of a frame buffer provided by userspace. There is no reason to require 4 buffers queued at all times for the driver to operate. Drop min_queued_buffers from the VIN driver to allow single-frame capture operations.
