Compiling the fsl-mc bus driver will yield a couple of static analysis
errors:
warning: symbol 'fsl_mc_msi_domain_alloc_irqs' was not declared
warning: symbol 'fsl_mc_msi_domain_free_irqs' was not declared.
warning: symbol 'its_fsl_mc_msi_init' was not declared.
warning: symbol 'its_fsl_mc_msi_cleanup' was not declared.
Since these are properly declared, but the header is not included, add
it in the source files. This way the symbol is properly exported.

This driver supports the Lantiq SSC SPI controller in master
mode. This controller is found on Intel (former Lantiq) SoCs like
the Danube, Falcon, xRX200, xRX300.
The hardware uses two hardware FIFOs one for received and one for
transferred bytes. When the driver writes data into the transmit FIFO
the complete word is taken from the FIFO into a shift register. The
data from this shift register is then written to the wire. This driver
uses the interrupts signaling the status of the FIFOs and not the shift
register. It is also possible to use the interrupts for the shift
register, but they will send a signal after every word. When using the
interrupts for the shift register we get a signal when the last word is
written into the shift register and not when it is written to the wire.
After all FIFOs are empty the driver busy waits till the hardware is
not busy any more and returns the transfer status.

Previously, we used the HW GID index in order to search the source GID
in the software GID cached table. In some cases, for example when
the MAC Address of the network interface is changed, the GID cached table
saves the old-IPv6-link-local GID at the end of the table.
When returning the old MAC address, the software GID cached table tries
to add the new IPv6-link-local GID, and when it identifies that the GID
already exists, the software GID cached does not add it. Thus a mismatch
occurs between the HW and the SW GID tables.
It resulted with sending traffic with the wrong source GID.
This commit fixes the issue by taking both from the HW table.
The problem can be reproduced with the following scenario:
Client:
# ifconfig ens6 2.2.2.5
# ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64
# ifconfig ens6 hw ether f4:52:14:61:a0:71
# ifconfig ens6 inet6 del 2001:0db8:0:f101::5/64

Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.
Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.
Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.
This patch doesn't add any new functionality.

Since function tables are a common target for attackers, it's best to keep
them in read-only memory. As such, this makes the CDROM device ops tables
const. This drops additionally n_minors, since it isn't used meaningfully,
and sets the only user of cdrom_dummy_generic_packet explicitly so the
variables can all be const.

The prox/range bits included in the Bluetooth reports from the Intuos Pro
were being ignored, leading to two issues. Firstly, the pen would never
announce a BTN_TOOL_PEN event with value 0, leaving userspace to believe
the pen was always active. Secondly, the driver would continue to send
events for data while the packet's "prox" bit was clear. This can lead
to sudden incorrect pointer jumps if the pen is slowly moved away from
the tablet surface.
