The current implementation to retrieve ACPI resources is faulty
and may cause issues that even can lead to non-booting systems.
When adding data from an ACPI device, the resources are already
assigned to the platform device. Therefore there is no need to
retrieve the resource list from ACPI and manually assign it to
the platform device. Also there shouldn't be any BIOS in the wild
anymore, that does not have resources added to the KEMPLD ACPI
data.
In particular this fixes an issue where the retrieval of the
resource list using /proc/ioports is disturbed and does not list
the assigned resource for the kempld device or even no resources
at all.
On some distributions this also leads to problems during system
initialization (e.g. with udev) and causes the system to not
boot at all.
I have reproduced the issue with the following kernel versions:
5.10.209
5.15.148
6.1.25
6.6.17
6.7.5
6.8-rc5
The patch applies to all of those versions and seems to resolve
the issue.

Process rise event last, to avoid stuck keys when multiple interrupts
are coalesced. This can happen typically when resuming from suspend
via power key press and holding the power button for a bit too short,
so that RISE an FALL IRQ flags are set before any interrupt routine
has a chance to run.
Input subsystem will interpret it as holding down a power key for
a long time, which leads to unintended initiation of shutdown UI
on some OSes.

receive_buf() is called from ttyport_receive_buf() that expects values
">= 0" from serdev_controller_receive_buf(), change its return type from
ssize_t to size_t.
The need for this clean-up was noticed while fixing a warning, see
commit 94d0539425 ("Bluetooth: btnxpuart: fix recv_buf() return value").
Changing the callback prototype to return an unsigned seems the best way
to document the API and ensure that is properly used.
GNSS drivers implementation of serdev receive_buf() callback return
directly the return value of gnss_insert_raw(). gnss_insert_raw()
returns a signed int, however this is not an issue since the value
returned is always positive, because of the kfifo_in() implementation.
gnss_insert_raw() could be changed to return also an unsigned, however
this is not implemented here as request by the GNSS maintainer Johan
Hovold.

As usual, Jiri has a bunch of refactoring and cleanups for the tty core
and drivers in here, along with the usual set of rs485 updates (someday
this might work properly...) Along with those, in here are changes for:
- sc16is7xx serial driver updates
- platform driver removal api updates
- amba-pl011 driver updates
- tty driver binding updates
- other small tty/serial driver updates and changes
All of these have been in linux-next for a while with no reported
issues.

The sysctrl driver was looking for an instance of the PM2301
charger but this has been deleted from the kernel and is not
used with the U8500 systems any more. Drop the string.
