From 072915b57a85e8d65e22be5595a639110afdcc90 Mon Sep 17 00:00:00 2001 From: Nikhil Devshatwar Date: Fri, 18 Nov 2016 21:20:19 -0200 Subject: [media] media: ti-vpe: vpe: Return NULL for invalid buffer type get_q_data can be called with different values for type e.g. vpe_try_crop calls it with the buffer type which gets passed from user space Framework doesn't check wheather its correct type or not If user space passes wrong type, kernel should not crash. Return NULL when the passed type is invalid.
