Subject: [PATCH 0/5] use idr kernel library instead of handles

From: Rene Sapiens <rene.sapiens@...com>

Use idr kernel library to send/receive node and stream ids to the
user instead of kernel address.
This id will be use to access the node and stream handles at the
kernel side, if id does not match to any handle
error -EFAULT is returned.

For processor handle, dspbridge driver will make sure
the handle is valid by using the handle stored in process context.

Ernesto Ramos (5):
  staging:ti dspbridge: use node id instead of kernel address
  staging:ti dspbridge: avoid errors if node handle is zero
  staging:ti dspbridge: use processor handle from context instead of
    user's
  staging:ti dspbridge: use stream id instead of kernel address
  staging:ti dspbridge: avoid errors if stream id is zero
