Hi,

On top of Linus' tree. This series fixes clang warnings.

Base commit: 8395ae05cb5a2e31d36106e8c85efa11cda849be ("Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi")

# Patch 1:

  Compiling with clang-16:

    drivers/acpi/acpi_lpit.c:142:6: error: no previous prototype \
    for function 'acpi_init_lpit' [-Werror,-Wmissing-prototypes]

    drivers/acpi/ioapic.c:212:6: error: no previous prototype \
    for function 'pci_ioapic_remove' [-Werror,-Wmissing-prototypes]

    drivers/acpi/ioapic.c:229:5: error: no previous prototype \
    for function 'acpi_ioapic_remove' [-Werror,-Wmissing-prototypes]

  Include "internal.h" to silence them.

# Patch 2:

  @num_carats is used for debugging, passed to the 'ACPI_DEBUG_PRINT()'
  macro. But this macro will expand to nothing when debug is disabled,
  resulting in the following (clang-16):

    drivers/acpi/acpica/nsaccess.c:295:6: error: variable 'num_carats' set \
    but not used [-Werror,-Wunused-but-set-variable]
          u32 num_carats;
              ^
    1 error generated.

  Move the variable declaration inside the else block to reduce the scope,
  then add '(void)num_carats' to silence the warning when debug is disabled.
