====================
Cleanups for ocelot/felix drivers
This patch set is an assorted collection of minor cleanups brought to
the felix DSA driver and ocelot switch library.
====================

Due to an apparently incorrect conflict resolution on my part in commit
54c3198460 ("net: mscc: ocelot: enforce FDB isolation when
VLAN-unaware"), "ocelot->ports[port]->is_dsa_8021q_cpu = false" was
supposed to be replaced by "ocelot_port_unset_dsa_8021q_cpu(ocelot, port)"
which does the same thing, and more. But now we have both, so the direct
assignment is redundant. Remove it.

Automated tools complain that felix_check_xtr_pkt() has logic to drain
the CPU queue on the reception of a PTP packet over Ethernet, yet it
returns an uninitialized error code in the case where the CPU queue was
empty.
This is not likely to happen (/possible if hardware works correctly),
but it isn't a fatal condition either. The PTP packet will be dequeued
from the CPU queue when the next PTP packet arrives. So initialize "err"
to 0 for the case where nothing was dequeued during this iteration.

The DSA ->port_rxtstamp() function is never called for PTP_CLASS_NONE:
dsa_skb_defer_rx_timestamp:
if (type == PTP_CLASS_NONE)
return false;
if (likely(ds->ops->port_rxtstamp))
return ds->ops->port_rxtstamp(ds, p->dp->index, skb, type);

node. Change the devm_gpiod_get_optional() to gpiod_get_optional() and
pass proper device node to it. The code already has a proper cleanup

TE-gpio is optional and if it is not found then gpiod_get_optional()
returns NULL. In such case the code will continue and try to convert NULL
gpiod to irq what in turn fails. The failure is then propagated and driver
is not registered.
Fix this by returning early from exynos_dsi_register_te_irq() if no
TE-gpio is found.

Commit 67d96729a9 ("riscv: Update Canaan Kendryte K210 device tree")
incorrectly removed two entries from the PLIC interrupt-controller node's
interrupts-extended property.
The PLIC driver cannot know the mapping between hart contexts and hart ids,
so this information has to be provided by device tree, as specified by the
PLIC device tree binding.
The PLIC driver uses the interrupts-extended property, and initializes the
hart context registers in the exact same order as provided by the
interrupts-extended property.
In other words, if we don't specify the S-mode interrupts, the PLIC driver
will simply initialize the hart0 S-mode hart context with the hart1 M-mode
configuration. It is therefore essential to specify the S-mode IRQs even
though the system itself will only ever be running in M-mode.
Re-add the S-mode interrupts, so that we get working IRQs on hart1 again.
