From 630caa23b75ca5d399791fa5a4d8d5f4adf81489 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Fri, 2 Dec 2011 21:55:04 -0300 Subject: [media] m5mols: Remove mode_save field from struct m5mols_info There is no need to keep this in the drivers' private data structure, an on the stack variable is enough. Also simplify a bit the ISP state switching function.
