The omap2 onenand driver is now available for compile-testing, which
uncovers a warning in configurations that have a 64-bit resource_size_t:
drivers/mtd/onenand/omap2.c: In function 'omap2_onenand_probe':
drivers/mtd/onenand/omap2.c:536:54: error: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'resource_size_t {aka long long unsigned int}' [-Werror=format=]
dev_err(dev, "Cannot reserve memory region at 0x%08x, size: 0x%x\n",
drivers/mtd/onenand/omap2.c:536:66: error: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t {aka long long unsigned int}' [-Werror=format=]
Changing the format string to the special %pR simplifies the code
and lets it do the right thing in that configuration, while avoiding
the warning.

Applied. I'll adjust my PR to include this fix.
