Subject: [PATCH AUTOSEL 5.2 068/185] dmaengine: iop-adma: use correct printk format strings

From: Arnd Bergmann <arnd@...db.de>

[ Upstream commit 00c9755524fbaa28117be774d7c92fddb5ca02f3 ]

When compile-testing on other architectures, we get lots of warnings
about incorrect format strings, like:

   drivers/dma/iop-adma.c: In function 'iop_adma_alloc_slots':
   drivers/dma/iop-adma.c:307:6: warning: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

   drivers/dma/iop-adma.c: In function 'iop_adma_prep_dma_memcpy':
>> drivers/dma/iop-adma.c:518:40: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'size_t {aka long unsigned int}' [-Wformat=]

Use %zu for printing size_t as required, and cast the dma_addr_t
arguments to 'u64' for printing with %llx. Ideally this should use
the %pad format string, but that requires an lvalue argument that
doesn't work here.
