Subject: [media] coda: fix error return value if v4l2_m2m_ctx_init fails
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=72720ffc74a58ce27ea237c729f38e6a966f2997;p=openwrt%2Fstaging%2Fblogic.git

[media] coda: fix error return value if v4l2_m2m_ctx_init fails

Use ret from the outer scope, instead of redefining it in the
conditional clause. That way the error value reaches the end of
the function as intended.
