why is "const u32 (*tab)[256]" not kerneldoc-able?

[Robert P. J. Day]

  when generating the kerneldoc manual kernel-api.html with "make
htmldocs", the two routines in lib/crc32.c that refer to a parameter
of type "const u32 (*tab)[256]" generate kerneldoc errors:

Warning(.//lib/crc32.c:148): No description found for parameter 'tab)[256]'
Warning(.//lib/crc32.c:148): Excess function parameter 'tab' description in 'crc32_le_generic'
Warning(.//lib/crc32.c:293): No description found for parameter 'tab)[256]'
Warning(.//lib/crc32.c:293): Excess function parameter 'tab' description in 'crc32_be_generic'
Warning(.//lib/crc32.c): no structured comments found

  kerneldoc content and declaration for one of them:

/**
 * crc32_le_generic() - Calculate bitwise little-endian Ethernet AUTODIN II
 *                      CRC32/CRC32C
 * @crc: seed value for computation.  ~0 for Ethernet, sometimes 0 for other
 *       uses, or the previous crc32/crc32c value if computing incrementally.
 * @p: pointer to buffer over which CRC32/CRC32C is run
 * @len: length of buffer @p
 * @tab: little-endian Ethernet table
 * @polynomial: CRC32/CRC32c LE polynomial
 */
static inline u32 __pure crc32_le_generic(u32 crc, unsigned char const *p,
                                          size_t len, const u32 (*tab)[256],
                                          u32 polynomial)
{

... snip ...

  so what is it about that declaration that causes kerneldoc to choke?
and because those two routines are the only kerneldoc content in that
source file, the kernel-api page generated for that file is just a
dummy page, reporting an error.

  thoughts?
