From 241fa6e42f5462a82f00ddf5169628a8c3976548 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 11 Oct 2011 11:54:26 -0300 Subject: [PATCH] [media] uvcvideo: GET_RES should only be checked for BITMAP type menu controls Currently it is also being checked for non BITMAP type menu controls, breaking the logitech LED control menu added by uvcdynctrl, as well as potentially breaking the powerline frequency menu.
