[PATCH 13/21] iommu: tegra: print dma_addr_t using %lld

From: Arnd Bergmann
Date: Thu Apr 25 2013 - 13:33:52 EST


The code was recently changed to work for builds with a 64 bit
dma_addr_t, but the printk unconditionally uses a format
string for an "long" variable, which is always wrong as
the dma_add_t is now either 'unsigned int' or 'unsigned long long'
depending on configuration.

The easiest solution is to cast the variable to u64 and print
it as a 64 bit value.
