Commit a674533078 ("tools lib traceevent: Split pevent_print_event()

pevent_print_event() into three functions.
The first function prints the comm, pid and CPU, the second prints the

But that commit added the printing of the CPU in the timestamp function,
which now causes pevent_print_event() to duplicate the CPU output.
Remove the redundant printing of the record's CPU from the timestamp

Indeed, without this patch, if GPIOLIB is not selected
devm_gpiod_get_optional() will return -ENOSYS and the driver probe
call will fail, regardless of the actual PHY hardware.
Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035),
only AT8030 presents the issues that commit 13a56b4493 ("net: phy:

Hence, only AT8030 should depend on GPIOLIB operating properly.

The driver of course "knows" that the chip's reset signal is active low,
so it drives the GPIO to 0 to reset the PHY and to 1 otherwise; however
all this will only work iff the GPIO is specified as active-high in the
device tree! I think both the driver and the device trees (if there are
any -- I was unable to find them) need to be fixed in this case...

GPS rfkill support via pre-2009 WMI interface uses hp_wmi_get_sw_state()
and hp_wmi_get_hw_state() to query its current hard and soft block state,
respectively.
In hp_wmi_get_sw_state() a mask is calculated which bit should be checked
in an int value returned by firmware to get current block state: 0x200 <<
(r * 8) which with r being 3 for GPS results in overflow and mask of zero.
The same goes for hp_wmi_get_hw_state().
This effectively means that GPS rfkill on this WMI interface is considered
always both hard and soft blocked.
Unfortunately, later when rfkill subsystem calls hp_wmi_set_block() to sync
this block to hardware firmware at least on my old nc6400 gets confused and
sets both hard and soft blocks on WiFi and BT.
This happens for example on hp-wmi module load.
Since due to overflow described above it is dubious that this ever worked
correctly and HP laptops with modems having GPS support seem to all have
been released well past year 2009 let's just remove GPS rfkill support via
pre-2009 WMI interface.

rfkill registration order in hp_wmi_rfkill_setup() is:
1) WiFi,
2) BT,
3) WWAN,
5) GPS.
Unregistration when cleaning up on error return should happen in reverse
order.
This means that: If BT rfkill fails to be allocated we possibly need to
first unregister WiFi rfkill before destroying it.
The same goes with (WWAN, BT) and (GPS, WWAN) pairs.
Also, if WWAN rfkill fails to register we need to (possibly) unregister BT
not the GPS one. And if GPS rfkill fails to register we need to unregister
WWAN not the BT one.
We never need to unregister GPS rfkill here since if GPS rfkill
registration succeeds this function returns without error so no cleanup is
necessary.

issue this SMBIOS request in order to receive WMI events, DMI matching
is used to whitelist the models which need it.

The Kconfig currently controlling compilation of this code is:

...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_pci_driver() uses the same init level priority as
builtin_pci_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We don't replace module.h with init.h since the file already has that.

FWIW, it appears that the DMI table may be a legacy thing and we

example, a whole lot of things map to KEY_PROG3 via the DMI table.
