[ Upstream commit 91d516d4de48532d967a77967834e00c8c53dfe6 ]
Increase size of queue_name buffer from 30 to 31 to accommodate
the largest string written to it. This avoids truncation in
the possibly unlikely case where the string is name is the
maximum size.

Introduced by commit 118d6298f6f0 ("net: mvpp2: add ethtool GOP statistics").
I am not flagging this as a bug as I am not aware that it is one.
Compile tested only.

[ Upstream commit 9f538b415db862e74b8c5d3abbccfc1b2b6caa38 ]
Register value persist after booting the kernel using
kexec which results in kernel panic. Thus clear the
BM pool registers before initialisation to fix the issue.
