The function blk_queue_max_hw_sectors() was removed in Linux v6.10 and
so add a test to conftest to see if this function is present or not to
allow the driver to build. The virtual-storage driver is currently
broken for Linux v5.19+ kernel due to other incompatibilities with these
newer kernels, but has been updated so that it still builds. Therefore,
allow the driver to build for Linux v6.10 while the driver is fixed
properly for these newer kernels.

[Issue]: CAN freezes/stops to send messages after restart from bus-off state.
Throws following log from kernel: "write: No buffer space available"
[Reason]: When message txfer starts, tx_object (which keeps track of active tx)
gets filled. If CAN goes to bus-off state, txfer remains incomplete for some
messages. In such case, tx_object bits will not get cleared. It will stop
adding more messages in controller RAM.
Along with tx_object, from network layer, there are socket echo buffers.
When CAN is initialized and up on network, netif_start_queue is pushed to start
transmission. When msg txfer starts, socket buffer gets filled and freed only
when txfer completes. During bus-off, since network queue remains ON, all the
queued msgs get filled in socket buffers and does not allow upcoming msgs.
Therefore we see "write: No buffer space available".
[Fix]: Clear tx_object when device goes to bus-off state and stop network queue.
Start network queue again during restart from bus-off.

Building the PCI EPF DMA test driver for Linux v6.9 is failing because
the parameters for the pci_epf_alloc_space() function has been updated
to pass the alignment value via the 'pci_epc_features' structure instead
of passing the value directly.
Instead of hard-coding the endpoint alignment in the EPF DMA test driver
use the 'pcie_epc_get_features()' function to retrieve the endpoint
features structure which has the endpoint alignment.
By using the conftest script to detect the parameters for the
pci_epf_alloc_space() function, we can then pass the appropriate
arguments to the pci_epf_alloc_space() function.

The compatibility layer was first introduced in Linux v4.13 by commit

that the newer "controller" based naming works for kernels from v4.13,
update the various SPI drivers to use the new naming for all current

When adding conftest tests for detecting if specific functions are
present, it is always better to check if the newly added function is
present versus the function that has been removed. The reason being that
is the newly added function is modified in the future then the conftest
tests can be extended to check for updates to the function.
Therefore, instead of checking if the function gpiochip_find() is
present, which was removed in Linux v6.7, check if the function
gpio_device_find() is present, which replaced gpiochip_find in Linux
v6.7.
