[PATCH -next] drm: simpledrm: print resource info using '%pr'

From: Randy Dunlap
Date: Wed May 12 2021 - 19:56:53 EST


struct resource start and end fields are not always long long,
so using %llx to print them can cause build warnings (below).
Fix these by using the special "%pr" for printing struct resource info.

../drivers/gpu/drm/tiny/simpledrm.c: In function ‘simpledrm_device_init_mm’:
../include/drm/drm_print.h:412:32: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘resource_size_t {aka unsigned int}’ [-Wformat=]
../drivers/gpu/drm/tiny/simpledrm.c:533:54: note: format string is defined here
drm_err(dev, "could not acquire memory range [0x%llx:0x%llx]: error %d\n",
~~~^
%x
