From cdf7bfa8926fb26d5900103ae09eb5f3eddb95cc Mon Sep 17 00:00:00 2001 From: Devin Heitmueller Date: Fri, 19 Jun 2009 00:20:28 -0300 Subject: [PATCH] V4L/DVB (12100): em28xx: make sure the analog GPIOs are set if we used a card hint In cases where the board had a default USB ID, we would not indentify the board until after the call to em28xx_set_mode(). As a result, for those boards the analog GPIOs were not being set before probing the i2c bus for devices (the probe would occur with the GPIOs being all high). Make a call to em28xx_set_mode() so that the GPIOs are set properly before probing the i2c bus for devices. This problem was detected with the EVGA inDtube, where the tvp5150 is not powered on unless GPIO1 is pulled low.
