no_llseek had been defined to NULL two years ago, in commit 868941b144
("fs: remove no_llseek")
To quote that commit,
At -rc1 we'll need do a mechanical removal of no_llseek -
git grep -l -w no_llseek | grep -v porting.rst | while read i; do
sed -i '/\<no_llseek\>/d' $i
done
would do it.
Unfortunately, that hadn't been done. Linus, could you do that now, so
that we could finally put that thing to rest? All instances are of the
form
.llseek = no_llseek,
so it's obviously safe.

This pull request contains some cleanups to the core and some mostly
minor updates to a bunch of drivers and device tree bindings. One thing
worth pointing out is that it contains an immutable branch containing
support for a new mfd chip (Analog Devices ADP5585) with several sub
drivers. So expect to get the four affected commits also from my fellow
MFD and GPIO maintainers.

Prepare ep93xx SOC gpio to convert into device tree driver:
- dropped banks and legacy defines
- split AB IRQ and make it shared
We are relying on IRQ number information A, B ports have single shared
IRQ, while F port have dedicated IRQ for each line.
Also we had to split single ep93xx platform_device into multiple, one
for each port, without this we can't do a full working transition from
legacy platform code into device tree capable. All GPIO_LOOKUP were
change to match new chip namings.

Replace comma between expressions with semicolons.

that is not the case here, it is seems best to use ';' unless ',' is

First of all, remove duplicate message that platform_get_irq()
does already print. Second, correct the error message when unable
to register a handler, which is broken in two ways:
1) the misleading 'get' vs. 'register';
2) missing '\n' at the end.
(Yes, for the curious ones, the dev_*() cases do not require '\n'
and issue it automatically, but it's better to have them explicit)
Fix all this here.

The mpc8xxx GPIO can generate an interrupt on state change. This
interrupt can be used to wake up the device from its sleep state if
enabled to do so. Add required support to the driver so that the GPIO
can be used in this way.
In order for the GPIO to actually function in this way, it is necessary
to also set the GPIO bit in the RCPM. This can be done via the device
tree fsl,rcpm-wakeup property.

Use the IS_ERR_OR_NULL() helper instead of open-coding a
NULL and an error pointer checks to simplify the code and
improve readability.
No functional changes are intended.

Besides the fact that (old) drivers use wrong definitions, e.g.,
GPIOF_DIR_IN instead of GPIOF_IN, shrink the legacy definitions
by killing those GPIOF_DIR_* completely.

Use dev_err_probe() to simplify the error path and unify a message
template.
Using this helper is totally fine even if err is known to never
be -EPROBE_DEFER.
The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.
