Subject: [media] cx88: drop cx88_free_buffer
X-Git-Tag: v3.19-rc1~126^2~280
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=999b3ceb849b5b9ed25739fea2e69adef09845c7;p=karo-tx-linux.git

[media] cx88: drop cx88_free_buffer

Remove this function. This makes all vb2 queues behave the same, which
simplifies comparing the various vb2 queue op implementations.
