git grep -E 'if .*\.p\W' found a couple of interesting candidates you
might want to check out:

drivers/i2c/i2c-core.c: if (unlikely(WARN_ON(!i2c_bus_type.p))) {
drivers/i2c/i2c-core.c: if (unlikely(WARN_ON(!i2c_bus_type.p)))
drivers/spmi/spmi.c: if (WARN_ON(!spmi_bus_type.p))

And this looks somewhat suspicious too, but could very well be OK for
all I know (very close to nothing :)

drivers/gpio/gpiolib-sysfs.c: if (!gpio_class.p) {
drivers/gpio/gpiolib-sysfs.c: if (!gpio_class.p)
