This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: powerpc/xive: add error return value to xive_smp_probe()
Date: Fri, 24 Jul 2026 10:28:47 +0800

xive_smp_probe() calls xive_init_ipis() which can fail, but its return
value is currently ignored.  Change xive_smp_probe() to return int so that
errors can be propagated to callers.

This is a preparatory patch for the next one.

No functional change yet; the return value is always 0 at this point.
