Subject: [PATCH, v2] ARM: omap2: gpmc: fix compilation warning

From: Vincent Stehlé <v-stehle@...com>

Fix the following compilation warning:

  arch/arm/mach-omap2/gpmc.c: In function 'gpmc_probe_generic_child':
  arch/arm/mach-omap2/gpmc.c:1477:4: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t' [-Wformat]

Hi,

Sorry for the late answer; it seems this is a bit more complicated after all,
as res.start can be 32b or 64b in LPAE. The common solution seems to be: cast
to long long in all cases and print accordingly. Would you like this better?

Best regards,

V.
