The driver name is available in device_driver::name. Right now,
drivers still have to report this piece of information themselves in
their devlink_ops::info_get callback function.

In order to factorize code, make devlink_nl_info_fill() add the driver
name attribute.

Now that the core sets the driver name attribute, drivers are not
supposed to call devlink_info_driver_name_put() anymore. Remove
devlink_info_driver_name_put() and clean-up all the drivers using this
function in their callback.

PEROUT_ENABLE_OUTPUT_MASK was there to allow us to enable/disable

<title>ACPI: make remove callback of ACPI driver void</title>

For bus-based driver, device removal is implemented as:
1 device_remove()-&gt;
2   bus-&gt;remove()-&gt;
3     driver-&gt;remove()

Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d571
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.

Now we have the situation that both 1 &amp; 2 of calling chain are
void-returned, so it does not make much sense for 3(driver-&gt;remove)
to return non-void to its caller.

So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.

This change, for itself, is for device drivers based on acpi-bus.

Now that all drivers have been converted to .adjfine, we can remove the
.adjfreq from the interface structure.

Convert all remaining drivers that still use .adjfreq to the newer .adjfine
implementation. These drivers are not straightforward, as they use
non-standard methods of programming their hardware. They are all converted
to use scaled_ppm_to_ppb to get the parts per billion value that their
logic depends on.

The ptp_phc implementation of .adjfreq is implemented in terms of a
straight forward "base * ppb / 1 billion" calculation.

Convert this to the newer .adjfine, updating the driver to use the recently
introduced adjust_by_scaled_ppm helper function.

A few PTP drivers implement a .adjfreq handler which indicates the
operation is not supported. Convert all of these to .adjfine.

Previously there was a fallback mode to flash firmware image without
proper header. But now we have different supported vendors and flashing
wrong image could destroy the hardware. Remove fallback mode and force
header check. Both vendors have published firmware images with headers.
