If registering the platform device fails, the lookup table is
removed in the error path. On module removal we would try to
remove the lookup table again. Fix this by setting priv->lookup
only if registering the platform device was successful.
In addition free the memory allocated for the lookup table in
the error path.

 "A workaround to suppress the continuous bus resets in the case that
  older devices are connected to the modern 1394 OHCI hardware and
  devices

  In IEEE 1394 Amendment (IEEE 1394a-2000), the short bus reset is added
  to resolve the shortcomings of the long bus reset in IEEE 1394-1995.
  However, it is well-known that the solution is not necessarily
  effective in the mixing environment that both IEEE 1394-1995 PHY and
  IEEE 1394a-2000 (or later) PHY exist, as described in section 8.4.6.2
  of IEEE 1394a-2000.

  The current implementation of firewire stack schedules the short bus
  reset when attempting to resolve the mismatch of gap count in the
  certain generation of bus topology. It can cause the continuous bus
  reset in the issued environment.

  The workaround simply uses the long bus reset instead of the short bus
  reset. It is desirable to detect whether the issued environment or
  not. However, the way to access PHY registers from remote note is
  firstly defined in IEEE 1394a-2000, thus it is not available in the
  case"

bvec_iter is embedded in other structures.

SETUP_RNG_SEED in setup_data is supplied by kexec and should
not be reserved in the e820 map.

Doing so reserves 16 bytes of RAM when booting with kexec.
(16 bytes because data->len is zeroed by parse_setup_data so only
sizeof(setup_data) is reserved.)

When kexec is used repeatedly, each boot adds two entries in the
kexec-provided e820 map as the 16-byte range splits a larger
range of usable memory. Eventually all of the 128 available entries
get used up. The next split will result in losing usable memory
as the new entries cannot be added to the e820 map.

My recent commit e5d00aaa ("selftests/powerpc: Check all FPRs in
fpu_preempt") inadvertently broke the fpu_signal test.

It needs to take into account that fpu_preempt now loads 32 FPRs, so
enlarge darray.

Also use the newly added randomise_darray() to properly randomise darray.

Finally the checking done in signal_fpu_sig() needs to skip checking
f30/f31, because they are used as scratch registers in check_all_fprs(),
called by preempt_fpu(), and so could hold other values when the signal
is taken.

Chip outputs are enabled[1] before actual reset is performed[2] which might
cause pin output value to flip flop if previous pin value was set to 1.
Fix that behavior by making sure chip is fully reset before all outputs are
enabled.

Flip-flop can be noticed when module is removed and inserted again and one of
the pins was changed to 1 before removal. 100 microsecond flipping is
noticeable on oscilloscope (100khz SPI bus).

For a properly reset chip - output is enabled around 100 microseconds (on 100khz
SPI bus) later during probing process hence should be irrelevant behavioral
change.

Nouveau deallocates a few buffers post GPU init which are required for GPU suspend/resume to function correctly.
This is likely not as big an issue on systems where the NVGPU is the only GPU, but on multi-GPU set ups it leads to a regression where the kernel module errors and results in a system-wide rendering freeze.

This commit addresses that regression by moving the two buffers required for suspend and resume to be deallocated at driver unload instead of post init.
