The eventfs_create_dir() function returns error pointers, it never returns
NULL. Update the check to reflect that.

Hello Steven Rostedt (Google),
The patch 5790b1fb3d67: "eventfs: Remove eventfs_file and just use
eventfs_inode" from Oct 4, 2023 (linux-next), leads to the following
Smatch static checker warning:
fs/tracefs/event_inode.c:782 eventfs_create_events_dir()

When a kprobe is attached to a function that's name is not unique (is
static and shares the name with other functions in the kernel), the
kprobe is attached to the first function it finds. This is a bug as the
function that it is attaching to is not necessarily the one that the
user wants to
Hi.
In the kernel source code, it exists different functions which share the same
name but which have, of course, different addresses as they can be defined in
different modules:
# Kernel was compiled with CONFIG_NTFS_FS and CONFIG_NTFS3_FS as built-in.

The NXP PTN36502 is used in the Fairphone 5 smartphone, add a driver for
it so we can soon enable DisplayPort over USB-C on this phone.

Changes in v2:
- Use FIELD_PREP+GENMASK for register values
- Move FIELD_GET for chip revision from macro to code (to align with
Document bindings for this Type-C USB 3.1 Gen 1 and DisplayPort v1.2

The PTN36502 can also run in GPIO mode where it is configured
differently, without any I2C connection, but this is not supported yet.

Short reason:
Without swapping the SBU lanes, on QCM6490 Fairphone 5 the
DisplayPort-over-USB-C doesn't work.
The Orient-Chip OCP96011 used in this phone is generally compatible with
FSA4480 but has a difference how AUX+/- should be connected to SBU1/2.
Long explanation, with my current

On some hardware designs the AUX+/- lanes are connected reversed to
SBU1/2 compared to the expected design by FSA4480.
Made more complicated, the otherwise compatible Orient-Chip OCP96011
expects the lanes to be connected reversed compared to FSA4480.
* FSA4480 block diagram shows AUX+ connected
Allow specifying data-lanes to reverse the muxing orientation between
AUX+/- and SBU1/2 where necessary by the hardware design.
In the mux there's a switch that needs to be controlled from the OS, and
it either connects AUX+ -> SBU1 and AUX- -> SBU2, or the reverse: AUX+
-> SBU2 and AUX- -> SBU1,
The Orient-Chip OCP96011 is generally compatible with the FSA4480, add a
compatible for it with the fallback on fsa4480.
However the AUX/SBU connections are expected to be swapped compared to
FSA4480, so document this in the data-lanes description.

This patch add reclaim stat:
nr_promote: nr_pages shrink before promote by folio_update_gen.
And then, use correct nr_scanned which evict_folios passed into
trace_mm_vmscan_lru_shrink_inactive.
Mistake info like this:
```
kswapd0-89[000]64.887613: mm_vmscan_lru_shrink_inactive:
nid=0
This patchset add a new reclaim_stat named nr_promote to observe
number folios which MGLRU promoted before shrink touch, and then
show in mm_vmscan_lru_shrink_inactive. Also, fix nr_scanned in MGLRU
trace into nr_taken. (patch1)
Base this trace, here are many folio promoted before shrink touch,
With nr_prmote trace, show that here are many folio
promoted before shrink check.
I just test by below cmd, and grep nr_reclaimed=0:
```
trace-cmd record -e vmscan:mm_vmscan_lru_shrink_inactive\
stressapptest -M 8096 -s 120 -m 1 -W
trace-cmd report | grep "nr_reclaim\=0"
```
