[PATCH] net: fix pch_gbe section mismatch warning

[Randy Dunlap]

From: Randy Dunlap <randy.dunlap@oracle.com>

Fix section mismatch warning by renaming the pci_driver variable to a
recognized (whitelisted) name.

WARNING: drivers/net/pch_gbe/pch_gbe.o(.data+0x1f8): Section mismatch in reference from the variable pch_gbe_pcidev to the variable .devinit.rodata:pch_gbe_pcidev_id
The variable pch_gbe_pcidev references
the variable __devinitconst pch_gbe_pcidev_id
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
