Subject: [PATCH 1/6] media: i2c: ths7303: remove init_enable option from pdata

From: Lad, Prabhakar <prabhakar.csengg@...il.com>

This patch removes init_enable option from pdata, the init_enable
was intended that the device should start streaming video immediately
but ideally the bridge drivers should call s_stream explicitly for such
devices to start video.
