From: Arnd Bergmann <arnd@xxxxxxxx>
I recently came across some new uses of the 'slave_id' field that
I had (almost) removed a few years ago. There are no legitimate
uses of this field in the kernel, only a few stale references and
two drivers that abuse the field as a side-channel between the
dmaengine driver and its client.
Let's change the xilinx and qualcomm drivers to use the documented
side-channel (peripheral_data) instead, and remove the remnants of
it to prevent new users from coming in.
As the last patch in the series depends on all the others, it would
be nice have everything merged into the dmaengine tree for v5.17.
