[PATCH] fbdev: mmp: print IRQ resource using %pR format string

[Arnd Bergmann]

resource_size_t cannot be printed using the %x format string
when we it is defined as u64:

drivers/video/fbdev/mmp/hw/mmp_ctrl.c: In function 'mmphw_probe':
drivers/video/fbdev/mmp/hw/mmp_ctrl.c:506:22: error: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'resource_size_t {aka long long unsigned int}' [-Werror=format=]
   dev_err(ctrl->dev, "%s: res %x - %x map failed\n", __func__,
                      ^
drivers/video/fbdev/mmp/hw/mmp_ctrl.c:506:22: error: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'resource_size_t {aka long long unsigned int}' [-Werror=format=]

This changes the format string to %pR, which is interpreted
by the printk implementation to pretty-print a resource
structure.
