[bug discuss] fjes driver call trace warning, "PNP0C02" used in fjes seems like a bug,

[Dongdong Liu]

Hi all:

The bug is recorded in https://bugs.linaro.org/show_bug.cgi?id=2292.

"PNP0C02" attached two modules drivers/pnp/system.c and 
drivers/net/fjes/fjes_main.c .
"fjes" driver lead to the call trace.

system.c:
static const struct pnp_device_id pnp_dev_table[] = {
        /* General ID for reserving resources */
        {"PNP0c02", 0},
        /* memory controller */
        {"PNP0c01", 0},
        {"", 0}
};

jes_main.c:
static const struct acpi_device_id fjes_acpi_ids[] = {
        {"PNP0C02", 0},
        {"", 0},
};

Both of the modules use id "PNP0C02" (case insensitive),

I used "PNP0C02" to mark motherboard reserved resource as below in UEFI.
Device (RES1)
{
        Name (_HID, "HISI0081") // HiSi PCIe RC config baseaddress
        Name (_CID, "PNP0C02") // Motherboard reserved resource
                Name (_CRS, ResourceTemplate (){
                        Memory32Fixed (ReadWrite, 0xb0080000 , 0x10000)
                })
}

I think that "PNP0C02" should be used to mark any motherboard reserved resource 
and not a specific network driver.
It seems like a bug in the "fjes" driver.

Thanks
