[ Upstream commit e30cef001da259e8df354b813015d0e5acc08740 ]
txgbe register clk which name is i2c_designware.pci_dev_id(), clk_name will be stored in clk_lookup_alloc. If PCIe bus number is larger than 0x39, clk_name size will be larger than 20 bytes. It exceeds clk_lookup_alloc MAX_DEV_ID limits. So the driver shortened clk_name.
