From f98598391246068359604718cd925020d62bb40e Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 18 Jul 2012 10:53:58 -0300 Subject: [media] ov2640: Don't access the device in the g_mbus_fmt operation The g_mbus_fmt operation only needs to return the current mbus frame format and doesn't need to configure the hardware to do so. Fix it to avoid requiring the chip to be powered on when calling the operation.
