From 650b939ecd3f0a1a9dc800155f7efadeb1794868 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 24 Mar 2015 14:30:53 -0300 Subject: [PATCH] [media] coda: move parameter buffer in together with context buffer allocation The parameter buffer is a per-context buffer, so we can allocate and free it together with the other context buffers during REQBUFS. Since this was the last context buffer allocated in coda-common.c, we can now move coda_alloc_context_buf into coda-bit.c.
