Captured video would be out of sync when using the adv7280 with the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) had to be configured properly to ensure BT.656-4 compatibility. An error in the adv7280 reference manual suggested that EAV/SAV mode was enabled by default, however upon inspecting register 0x31, it was determined to be disabled by default.

In dvb_usb_i2c_init, if i2c_add_adapter fails, it only prints an error message, and then continues to set DVB_USB_STATE_I2C. This affects the logic of dvb_usb_i2c_exit, which leads to that, the deletion of i2c_adap even if the i2c_add_adapter fails. Fix this by returning at the failure of i2c_add_adapter and then move dvb_usb_i2c_exit out of the error handling code of dvb_usb_i2c_init.

CAL RX has a single sink and a single source pad. To support multiple streams, we will have multiple source pads (up to 8, one for each CAL context). Change the driver to allow creating more source pads and change the code accordingly to handle multiple source pads. We still keep CAL_CAMERARX_NUM_SOURCE_PADS as 1, and the behavior is unchanged. Also rename CAL_CAMERARX_PAD_SOURCE to CAL_CAMERARX_PAD_FIRST_SOURCE to highlight that it's the first source. Signed-off-by:

When starting streaming the driver currently programs the buffer address to the CAL base-address register and assigns the buffer pointer to ctx->dma.pending.

Somewhere along the way the context uninitialization has gone a bit odd: * We have cal_ctx_create() but no matching destroy call, but we still need to call cal_ctx_v4l2_cleanup() for each context. * We have cal_media_cleanup() which calls cal_ctx_v4l2_cleanup() for all contexts, but cal_media_init() is not where the contexts are created. * The order of uninit steps in cal_remove() is different than the error handling path in cal_probe(). * cal_probe()'s error handling calls cal_ctx_v4l2_cleanup() for each context, but also calls cal_media_clean(), doing the same context cleanup twice. So fix these, by introducing cal_ctx_destroy(), and using that in appropriate places instead of calling cal_ctx_v4l2_cleanup() in cal_media_clean(). Also use normal kzalloc (and kfree) instead of devm version as we anyway do manual cleanup for each context. Signed-off-by:
