Hi
From: Colin Ian King colin.king@canonical.com
The call to rsnd_node_count can potentially return a zero node count so add a check for this corner case. (Note that the two other calls to rsnd_node_count in the kernel perform this check, so I think it justifies adding this). This avoids using a zero nr in a devm_kcalloc call.
I don't have a problem with the patch, but really the code works fine as is. A better commit message is:
Most callers of_get_child_count() check that "nr" is non-zero so it causes a static checker warning when we don't do that here. This doesn't cause a problem or a crash, but having zero SSUIes (What's plural of ssui?) doesn't make sense either so let's add a check.
For the code
