[SRU][Xenial][PATCH 0/1] Linux 4.4.155 stable release build is broken on ppc64

[Kleber Sacilotto de Souza]

BugLink: https://bugs.launchpad.net/bugs/1795662

== SRU Justification ==
The 4.4.y stable backport c9fadf27006b for upstream commit 1bd6a1c4b80a
("powerpc/fadump: handle crash memory ranges array index overflow"),
cherry-picked for Xenial as part of bug 1792419, introduces a build failure
on ppc by returning a int in a void function. In 4.4.y register_fadump()
returns void because 98b8cd7f7564 ("powerpc/fadump: Return error when fadump
registration fails") hasn't been backported for this stable release.

== Fix ==
98b8cd7f7564 ("powerpc/fadump: Return error when fadump registration fails")

Backport needed only for context adjustment.

== Regression Potential ==
Low. The patch only handles the error return by some function and adds an
additional error message. Limited to powerpc.

== Test Case ==
Compile the kernel for powerpc (tested with ppc64el).
