[PATCH AUTOSEL 5.16 01/59] media: staging: media: zoran: move videodev alloc

by Sasha Levin

From: Corentin Labbe <clabbe(a)baylibre.com> [ Upstream commit 82e3a496eb56da0b9f29fdc5b63cedb3289e91de ] Move some code out of zr36057_init() and create new functions for handling zr->video_dev. This permit to ease code reading and fix a zr->video_dev memory leak.
