From 2cf251c0c3961bd467e086033c6073ef62b29b02 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 9 Jul 2015 07:10:20 -0300 Subject: [PATCH] [media] coda: reuse src_bufs in coda_job_ready The v4l2_m2m_num_src_bufs_ready() function is called in multiple places in coda_cob_ready, and there already is a variable src_bufs that is assigned to its result. Move it to the beginning and use it everywhere.
