pci: pci-mvebu: Use '%pa' for printing 'phys_addr_t' type
PATCH v2 1/1 pci: pci-mvebu: Use '%pa' for printing 'phys_addr_t' type
From: Fabio Estevam <[email protected]>
Fix the following build warning that happens when building multi_v7_defconfig with CONFIG_ARM_LPAE=y:
drivers/pci/host/pci-mvebu.c:334:5: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'phys_addr_t' [-Wformat=]
Fix the warning by using '%pa' to printing 'phys_addr_t' type. While at it, also use the more standard notation [mem 0x - 0x] for memory region.
---
Changes since v1:
- use the [mem 0x - 0x] notation

Dear Fabio Estevam,

Are you sure '&base + sz' works here? %pa needs a reference as argument, so &base looks good. But '&base + sz' means you will print the value which is at the address of base, to which 'sz' is added, which is not what we want here. Probably you need something like:
phys_addr_t end = base + sz;
and then use '&end'.
Or I am missing something?

I agree with your suggestion.
Thanks.
