[ Upstream commit 4d6d26537940f3b3e17138987ed9e4a334780bf7 ]
The c_can_handle_bus_err() function was incorrectly incrementing only the
receive error counter, even in cases of bit or acknowledgment errors that
occur during transmission. The patch fixes the issue by incrementing the
appropriate counter based on the type of error.

[ Upstream commit badccd49b93bb945bf4e5cc8707db67cdc5e27e5 ]
The MAC address of VF can be configured through the mailbox mechanism of
ENETC, but the previous implementation forgot to set the MAC address in
net_device, resulting in the SMAC of the sent frames still being the old
MAC address. Since the MAC address in the hardware has been changed, Rx
cannot receive frames with the DMAC address as the new MAC address. The
most obvious phenomenon is that after changing the MAC address, we can
see that the MAC address of eno0vf0 has not changed through the "ifconfig
eno0vf0" command and the IP address cannot be obtained .

Since the report buffer is used by all kinds of drivers in various ways, let's
zero-initialize it during allocation to make sure that it can't be ever used
to leak kernel memory via specially-crafted report.

To eventually get rid of all legacy drivers convert this driver to the
modern world implementing .apply(). The commit which brings these
changes is `5ec803edcb703fe379836f13560b79dfac79b01d` on the uplink
kernel.

Assigns device data to `s3c_wdt[cluster_index]` only when probe function
completes. Several functions of s3c2410_wdt use the existence of
`s3c_wdt[*]` to decide whether the device data is ready to be accessed.
This causes an invalid access issue as long as the probe function puts
device data to `s3c_wdt[cluster_index]` before completely preparing the
content. Fixes the issue by rearranging the assignment order.
