Marc Dietrich 68fae2f3df staging: nvec: remove managed resource from PS2 driver This basicly reverts commit `e534f3e9` (staging:nvec: Introduce the use of the managed version of kzalloc). Serio struct should never by managed because it is refcounted. Doing so will lead to a double free oops on module remove.

NVEC: An NVidia compliant Embedded Controller Protocol Implementation

This is an implementation of the NVEC protocol used to communicate with an
embedded controller (EC) via I2C bus. The EC is an I2C master while the host
processor is the I2C slave. Requests from the host processor to the EC are
started by triggering a gpio line.

There is no written documentation of the protocol available to the public,
but the source code[1] of the published nvec reference drivers can be a guide.
This driver is currently only used by the AC100 project[2], but it is likely,
that other Tegra boards (not yet mainlined, if ever) also use it.
