From: Arnd Bergmann <arnd@xxxxxxxx> Directly dividing a 64-bit value is not allowed on 32-bit architectures in the kernel. arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: drivers/bluetooth/btintel_pcie.o: in function `btintel_pcie_suspend_late': btintel_pcie.c:(.text+0x224): undefined reference to `__aeabi_ldivmod' Since this is a ktime_t value and dividing by 1000 gives a microsecond number, just convert it into microseconds using the appropriate helper.
