This warning option is now enabled by default, causing a few build regressions
in combination with the newly added pvr driver:

drivers/gpu/drm/imagination/pvr_device.c:130:6: error: no previous prototype for 'pvr_device_process_active_queues' [-Werror=missing-prototypes]
  130 | void pvr_device_process_active_queues(struct pvr_device *pvr_dev)
      |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/gpu/drm/imagination/pvr_fw_meta.c:33:1: error: no previous prototype for 'pvr_meta_cr_read32' [-Werror=missing-prototypes]
   33 | pvr_meta_cr_read32(struct pvr_device *pvr_dev, u32 reg_addr, u32 *reg_value_out)

Mark pvr_device_process_active_queues and pvr_gpuvm_free static as they are only used
in the file they are defined in, and include the correct header for the pvr_meta_cr_read32
declaration.

The array size calculation in pvr_vm_mips_fini() appears to be incorrect based on
taking the size of the pointer rather than the size of the array, which manifests
as a warning about signed integer overflow:

Just use the number of array elements directly here, and in the corresponding
init function for consistency.

Hello Arnd,

Thanks for the patch.  I'm slightly concerned that we've not seen this warning when
building here.  I guess we need to check our CI settings...

This was previously enabled only when building with either
"make W=1" or "make C=1", but not the default build, which
explains why it only showed up after the merge into linux-next
that has the corresponding scripts/Makefile.extrawarn change.

It would still be a good idea to add the extra compiler (W=1)
and sparse (C=1) warnings in your CI system and address all
other issues that might uncover.

Hello Arnd,

Thanks for this.  However, I fixed these in a patch a few minutes before you sent
yours.  I'm not sure what normally happens in these circumstances, but as my patch has
the kernel robot tags and a few additional fixes, I think we should probably use that
one.

Thanks,
Donald

Sure, that's fine. If you don't mind rebasing, just add a
"Reported-by: Arnd Bergmann <arnd@arndb.de>" line as well.

I tend to create a bug fix for any build regressions I see as
part of building randconfig kernels, but it's normal that the
mainainers have already fixed the same bug before I send my
patch, or that there is a better solution than what I come up
with.

Will do! In fact Maxime just told me to resubmit as a series anyway.
