Currently tda998x_encoder_destroy() calls cec_write() and reg_clear(), as part of the release procedure. Such calls need to access the I2C bus and therefore, we need to call them before drm_i2c_encoder_destroy() which unregisters the I2C device.
This commit moves the latter so it's done afterwards.

You really should have sent this with me in the To: header as I'm now the maintainer of this driver. Yes, this is a valid fix, and I'll apply it shortly. Thanks.
Sorry about that, I'm still kind of new to this whole deal. I'll keep it mind for future patches.
Thanks, Guido
