The kirin driver only needs the device data, not the whole struct
of_device_id. Use of_device_get_match_data() instead of of_match_device().
No functional change intended.

When a stop is requested on a crash, it is useless to try to shutdown it
gracefully, it is crashed.
In this case don't send the STM32_MBX_SHUTDOWN mailbox message that
will block the recovery during 500 ms, waiting an answer from the

The function to retrieve battery info (from the device tree) assumes
we have a static info struct that gets populated by calling into
power_supply_get_battery_info().
This is awkward since I want to support tables of static battery
info by just assigning a pointer to all info based on e.g. a
compatible value in the device tree.
We also have a mixture of static and dynamically allocated
variables here.
Bite the bullet and let power_supply_get_battery_info() allocate
also the memory used for the very top level
struct power_supply_battery_info container. Pass pointers
around and lifecycle this with the psy device just like the
stuff we allocate inside it.
Change all current users over.
As part of the change, initializers need to be added to some
previously uninitialized fields in struct
power_supply_battery_info.

Bugzilla #213839 reports a 7-port hub that doesn't work properly when
devices are plugged into some of the ports; the kernel goes into an
unending disconnect/reinitialize loop as shown in the bug report.
This "7-port hub" comprises two four-port hubs with one plugged into
the other; the failures occur when a device is plugged into one of the
downstream hub's ports. (These hubs have other problems too. For
example, they bill themselves as USB-2.0 compliant but they only run
at full speed.)
It turns out that the failures are caused by bugs in both the kernel
and the hub. The hub's bug is that it reports a different
bmAttributes value in its configuration descriptor following a remote
wakeup (0xe0 before, 0xc0 after -- the wakeup-support bit has
changed).
The kernel's bug is inside the hub driver's resume handler. When
hub_activate() sees that one of the hub's downstream ports got a
wakeup request from a child device, it notes this fact by setting the
corresponding bit in the hub->change_bits variable. But this variable
is meant for connection changes, not wakeup events; setting it causes
the driver to believe the downstream port has been disconnected and
then connected again (in addition to having received a wakeup
request).
Because of this, the hub driver then tries to check whether the device
currently plugged into the downstream port is the same as the device
that had been attached there before. Normally this check succeeds and
wakeup handling continues with no harm done (which is why the bug
remained undetected until now). But with these dodgy hubs, the check
fails because the config descriptor has changed. This causes the hub
driver to reinitialize the child device, leading to the
disconnect/reinitialize loop described in the bug report.
The proper way to note reception of a downstream wakeup request is
to set a bit in the hub->event_bits variable instead of
hub->change_bits. That way the hub driver will realize that something
has happened to the port but will not think the port and child device
have been disconnected. This patch makes that change.

When the USB core code for getting root-hub status reports was
originally written, it was assumed that the hub driver would be its
only caller. But this isn't true now; user programs can use usbfs to
communicate with root hubs and get status reports. When they do this,
they may use a transfer_buffer that is smaller than the data returned
by the HCD, which will lead to a buffer overflow error when
usb_hcd_poll_rh_status() tries to store the status data. This was
discovered by syzbot:
BUG: KASAN: slab-out-of-bounds in memcpy include/linux/fortify-string.h:225 [inline]
BUG: KASAN: slab-out-of-bounds in usb_hcd_poll_rh_status+0x5f4/0x780 drivers/usb/core/hcd.c:776
Write of size 2 at addr ffff88801da403c0 by task syz-executor133/4062
This patch fixes the bug by reducing the amount of status data if it
won't fit in the transfer_buffer. If some data gets discarded then
the URB's completion status is set to -EOVERFLOW rather than 0, to let
the user know what happened.

Add support for R-Car S4-8. We can reuse R-Car V3U code so that
renames variable names as "gen4".
Note that some registers of R-Car V3U do not exist on R-Car S4-8,
but none of them are used by the driver for now.

Use dma_set_mask_and_coherent() instead of unrolling it with some
dma_set_mask()+dma_set_coherent_mask().
Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never
fail if dev->dma_mask is non-NULL.
So, if it fails, the 32 bits case will also fail for the same reason.
That said, 'high_dma' can only be 1 after a successful
dma_set_mask_and_coherent().
Simplify code and remove some dead code accordingly, including a now
useless parameter to vxge_device_register().
