From: Laurent Pinchart Date: Wed, 18 Jul 2012 13:54:01 +0000 (-0300) Subject: [media] soc_camera: Don't call .s_power() during probe X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=37ad4e734bbc27ad1bec2d1cc3ffaa79b1def262;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git [media] soc_camera: Don't call .s_power() during probe The .s_power() call only covers the .g_mbus_fmt() operation call. Several clients required to be powered on to retrieve the current mbus format but have now been fixed. The .s_power() call is thus not needed anymore and can be removed.
