Yes, I know that.  What was bothering me was why it wasn't showing up in
my build tests which normally include allmodconfig.  I just realised
that I'm still suppressing those tests because mainline failed to build
an allmodconfig due to:

/build/stage/linux/drivers/dma/mmp_pdma.c:1188:14: error: shift count >= width o
f type [-Werror,-Wshift-count-overflow]
 1188 |         .dma_mask = DMA_BIT_MASK(64),   /* force 64-bit DMA addr capabil
ity */
      |                     ^~~~~~~~~~~~~~~~
/build/stage/linux/include/linux/dma-mapping.h:93:54: note: expanded from macro 
'DMA_BIT_MASK'
   93 | #define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
      |                                                      ^ ~~~

and never gets far enough into the build to show anything else.  I think
that subsequently got fixed in mainline but I didn't merge up yet.
