Switch all drivers accessing sub-device state to use the stream-aware functions. We will soon remove the old ones. This patch has been generated using the following Coccinelle script: ---------8<------------ @@ expression E1, E2, E3; @@ - v4l2_subdev_get_pad_format(E1, E2, E3) + v4l2_subdev_state_get_format(E2, E3) @@ expression E1, E2, E3; @@ - v4l2_subdev_get_pad_crop(E1, E2, E3) + v4l2_subdev_state_get_crop(E2, E3) @@ expression E1, E2, E3; @@ - v4l2_subdev_get_pad_compose(E1, E2, E3) + v4l2_subdev_state_get_compose(E2, E3) @@ expression E1, E2, E3; @@ - v4l2_subdev_get_try_format(E1, E2, E3) + v4l2_subdev_state_get_format(E2, E3) @@ expression E1, E2, E3; @@ - v4l2_subdev_get_try_crop(E1, E2, E3) + v4l2_subdev_state_get_crop(E2, E3) @@ expression E1, E2, E3; @@ - v4l2_subdev_get_try_compose(E1, E2, E3) + v4l2_subdev_state_get_compose(E2, E3) ---------8<------------ Additionally drivers/media/i2c/s5k5baf.c and drivers/media/platform/samsung/s3c-camif/camif-capture.c have been manually changed as Coccinelle didn't. Further local variables have been removed as they became unused as a result of the other changes. Also Coccinelle introduced indentation by space in files drivers/media/i2c/st-mipid02.c and drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also corrected.
