      tipc: checking for NULL instead of IS_ERR() · c75e427d
      Dan Carpenter authored 
      The tipc_alloc_conn() function never returns NULL, it returns error
pointers, so I have fixed the check.

Fixes: 14c04493 ("tipc: add ability to order and receive topology events in driver")

====================
net: sh_eth: add R-Car Gen[12] fallback compatibility strings

Add fallback compatibility strings for R-Car Gen 1 and 2.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.

We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.

For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.

Changes since v1:
* Correct typos in changelogs
* Consistently use tabs for indentation in bindings document
* Enhance readability of description of bindings usage

Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks.  The
approach that has been consistently taken for other IP blocks is to name
common code, compatibility strings and so on after R-Car Gen2.

      net: sh_eth: rename name structures as rcar_gen[12]_* · 6c4b2f7e
      Simon Horman authored 
      Rename structures describing R-Car SoCs as rcar_gen[12]_*
rather than r8a77[79]x_*. This seems a little easier on the
eyes. And will make things slightly cleaner in a follow-up
patch that adds fallback-compatibility strings for these SoCs.

Note that R-Car Gen2 and RZ/G1 have many compatible IP blocks.  The
approach that has been consistently taken for other IP blocks is to name
common code, compatibility strings and so on after R-Car Gen2.

Also rename sh_eth_set_rate_r8a777x as sh_eth_set_rate_rcar as
it it is used by the R-Car generations supported by the driver.

This patch should have no run-time effect and
is compile-tested only.
