4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Anton Vasilyev <vasil...@ispras.ru> [ Upstream commit 5958fde72d04e7b8c6de3669d1f794a90997e3eb ] goldfish_fb_probe() allocates memory for fb, but goldfish_fb_remove() does not have deallocation of fb, which leads to memory leak on probe/remove. The patch adds deallocation into goldfish_fb_remove(). Found by Linux Driver Verification project (linuxtesting.org).
