Krzysztof Kozlowski 0e777366fb mfd: Drop owner assignment from i2c_drivers
i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

Lee Jones b3fff1770a mfd: tps65912: Convert to managed resources for allocating memory
Saves on code and simplifies the driver, as these resources are now
tracked and freed automatically when the driver is realised.

Axel Lin 63c8a58d22 mfd: Fix off-by-one value range checking for tps65912_i2c_write
If bytes == (TPS6591X_MAX_REGISTER + 1), we have a buffer overflow when
doing memcpy(&msg[1], src, bytes).
