Hi Guennadi, since commit 9aea470b399d797e88be08985c489855759c6c60 "soc-camera: switch I2C subdevice drivers to use v4l2-clk", the em28xx driver fails to register the ov2640 subdevice (if needed). The reason is that v4l2_clk_get() fails in ov2640_probe(). Does the em28xx driver have to register a (pseudo ?) clock first ?
