last-minute misc ddbridge related changed

From: Daniel Scheller <[email protected]>

This small series improves on a few things related to the recently merged ddbridge driver update:

stv0910:
* add an explanation for the mutex_lock needs in gate_ctrl() and release the lock in case of I2C ctrl errors
* announce 100Ksyms/s as minimum symbol rate
ddbridge:
* fix the teardown and deregistration order wrt the i2c_client usage
* fix most warnings reported by sparse (sparse still reports four spinlock/context warnings, that code will be kept as-is - there won't be locking problems since the checked pointers won't suddenly vanish)
staging/cxd2099:
* disable buffer mode by default and make that controllable by a module parameter (suggested, requested and tested by Jasmin, modparm switch done by me)

Please pull these patches in for the 4.14 merge window, together with the two ([1], [2]) remaining ones on patchwork - thank you very much!
