From 51ae23df428b94654dfb778bf70ca327a6aa83a0 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 18 Apr 2012 06:12:57 -0300 Subject: [PATCH] [media] gspca_pac7311: Make sure exposure changes get applied immediately It turns out that the flush to sensor command needs to be done per register bank. We were missing one such flush in set_exposure, causing exposure changes to only show up when another setting in the same bank also got changed.
