of: Drop superfluous ULL suffix for ~0
There is no need to specify a "ULL" suffix for "all bits set": "~0" is sufficient, and works regardless of type. In fact adding the suffix makes the code more fragile. Fixes: 48ab6d5d1f09 ("dma-mapping: fix 32-bit overflow with CONFIG_ARM_LPAE=n") Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
