Subject: [media] coda: reuse src_bufs in coda_job_ready
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2cf251c0c3961bd467e086033c6073ef62b29b02;p=deliverable%2Flinux.git
[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.
