[GIT PULL 00/16] stm class: Updates for 4.20

[Alexander Shishkin]

Hi Greg,

These are the STM device class updates for the char-misc-next. No
dependencies in this patchset, it can be either pulled directly or
applied, the individual patches follow.

These are basically the MIPI SyS-T protocol and all the necessary
infrastructure changes.

These were aired previously; they also address review comments from
Mathieu, who also gave his Tested-By for the series. Also I received
a Reviewed-By from Andy for the memcat_p() stuff, like you asked.

As usual, these are aiaiai-clean (sparse/smatch/coccinelle/cppcheck).
Please consider pulling or applying. Thanks!

The following changes since commit 5b394b2ddf0347bef56e50c69a58773c94343ff3:

  stm class: Use memcat_p() (2018-10-05 14:59:08 +0300)

----------------------------------------------------------------
stm class: Updates for 4.20

These are:
  * infrastructure changes to introduce the concept of "protocol driver"
  * factoring out the existing framing pattern into a protocol driver
  * adding a new protocol driver for MIPI SyS-T protocol
  * documentation updates
  * adding a helper to paste 2 pointer arrays together: memcat_p()
