Vaittinen <matti.vaittinen@fi.rohmeurope.com>:
Add maintainer entries to a few ROHM devices and Linear Ranges
Linear Ranges helpers were refactored out of regulator core to lib so
that other drivers could utilize them too. (I guess power/supply drivers
and possibly clk drivers can benefit from them). As regulators is
currently the main user it makes sense the changes to linear_ranges go
through Mark's tree.
During past two years few ROHM PMIC drivers have been added to
mainstream. They deserve a supporter from ROHM side too :)
Patch 1:
Maintainer entries for few ROHM IC drivers
Patch 2:
Maintainer entry for linear ranges helpers

The BCM2835aux SPI driver uses devm_spi_register_master() on bind.
As a consequence, on unbind, __device_release_driver() first invokes
bcm2835aux_spi_remove() before unregistering the SPI controller via
devres_release_all().
This order is incorrect: bcm2835aux_spi_remove() turns off the SPI
controller, including its interrupts and clock. The SPI controller
is thus no longer usable.
When the SPI controller is subsequently unregistered, it unbinds all
its slave devices. If their drivers need to access the SPI bus,
e.g. to quiesce their interrupts, unbinding will fail.
As a rule, devm_spi_register_master() must not be used if the
->remove() hook performs teardown steps which shall be performed
after unbinding of slaves.
Fix by using the non-devm variant spi_register_master(). Note that the
struct spi_master as well as the driver-private data are not freed until
after bcm2835aux_spi_remove() has finished, so accessing them is safe.

When an SPI controller unregisters, it unbinds all its slave devices.
For this, their drivers may need to access the SPI bus, e.g. to quiesce
interrupts.
However since commit ffbbdd21329f ("spi: create a message queueing
infrastructure"), spi_destroy_queue() is executed before unbinding the
slaves. It sets ctlr->running = false, thereby preventing SPI bus
access and causing unbinding of slave devices to fail.
Fix by unbinding slaves before calling spi_destroy_queue().

When mapping a LPI, the ITS driver picks the first possible
affinity, which is in most cases CPU0, assuming that if
that's not suitable, someone will come and set the affinity
to something more interesting.
It apparently isn't the case, and people complain of poor
performance when many interrupts are glued to the same CPU.
So let's place the interrupts by finding the "least loaded"
CPU (that is, the one that has the fewer LPIs mapped to it).
So called 'managed' interrupts are an interesting case where
the affinity is actually dictated by the kernel itself, and
we should honor this.

The SDEI handler save/restores the addr_limit using set_fs(). It isn't
very clear why. The reason is to mirror the arch code's entry assembly.
The arch code does this because perf may access user-space, and
inheriting the addr_limit may be a problem.

qib_create_port_files(), the function kobject_put() is not called for the

The whole ethertype filtering code is implemented in igc_ethtool.c and
mixes logic from ethtool and core parts. This patch refactors it so core
logic is moved to igc_main.c, aligning the ethertype filtering code
organization with the rest of the filtering code from the driver (MAC
address and VLAN priority).
Besides moving code to igc_main.c, this patch also does some minor
improvements to the code. Below are some highlights.
In case all filters are already in use and the user tries to add another
filter, we return -ENOSPC instead of -EINVAL so a more meaningful error
code is provided. This also aligns with the behavior implemented in MAC
address filtering code.
With this code refactoring, 'etype_bitmap' array in struct igc_adapter
and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore
and are removed.
Log messages are added to help debugging the ethertype filtering code.

The suspend callback enables/disables PCI wake
on the basis of "cp->wol_enabled" variable
which is unknown to PCI core. To utilise its
need, call device_set_wakeup_enable().

With legacy PM hooks, it was the responsibility
of a driver to manage PCI states and also
device's power state. The generic approach is
to let PCI core handle the work.
PCI core passes "struct device*" as an argument
to the .suspend() and .resume() callbacks. As
these callabcks work with "struct net_device*",
extract it from "struct device*" using
dev_get_drv_data().

The whole VLAN priority filtering code is implemented in igc_ethtool.c
and mixes logic from ethtool and core parts. This patch refactors it so
core logic is moved to igc_main.c, aligning the VLAN priority filtering
code organization with the MAC address filtering code.
This patch also takes the opportunity to add some log messages to ease
debugging.

For backwards compatibility it may be required for the firmware to

the host. Combine the host feature bits and firmware feature bits
and write this back to the firmware.

The I225 controller supports Rx queue assignment based on VLAN priority
only. Other Tag Control Information (TCI) are valid, but not supported
by the driver. So this patch changes the returning code from igc_add_
ethtool_nfc_entry() to -EOPNOTSUPP in order to provide more meaningful
information on why the function failed.
It also adds a debug messages to give the user a hint about what went
wrong with the NFC setup.

The skx_edac driver wrongly uses the mtr register to retrieve two fields
close_pg and bank_xor_enable. Fix it by using the correct mcmtr register
to get the two fields.

Device id 0927 is the RTL8153B-based component of the 'Surface USB-C to
Ethernet and USB Adapter' and may be used as a component of other devices
in future. Tested and working with the r8152 driver.
Update the cdc_ether blacklist due to the RTL8153 'network jam on suspend'
issue which this device will cause (personally confirmed).

In bmac_get_station_address, We're reading two bytes at a time from ROM,
but we do that six times, resulting in 12 bytes of read & writes. This
means we will write off the end of the six-byte destination buffer.
This change fixes the for-loop to only read/write six bytes.
Based on a proposed fix from Finn Thain <fthain@telegraphics.com.au>.
