[PATCH 2/2] crypto: sahara: fix debug output for 64-bit dma_addr_t

Arnd Bergmann

The sahara_dump_descriptors and sahara_dump_links functions attempt
to print a dma_addr_t value with a 0x%08x format string, which
produces a warning when dma_addr_t is 64-bit wide:

drivers/crypto/sahara.c:419:120: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=]

This changes the code to use the %pad format string that is meant
for dma_addr_t, which avoids the warning and gives us the correct
output in all configurations.
