Subject: rt2x00: rt2800pci: use separate read_eeprom callback for SoC devices
X-Git-Tag: v4.0~2533^2~3^2^2~319
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=68597ea8674bd6c8983abc2a73e1e707af85f38e;p=platform%2Fkernel%2Flinux-amlogic.git

rt2x00: rt2800pci: use separate read_eeprom callback for SoC devices

Rename the 'rt2800pci_read_eeprom_soc function' to
'rt2800soc_read_eeprom' and use that directly in the
SoC specific 'rt2800_ops' structure. Also move the
'rt2800pci_eeprom_read' function into an 'ifdef PCI'
section and remove the 'rt2800pci_read_eeprom_soc'
call from that.

Additionally, remove the dummy inline eeprom functions.
Those are not used anymore.
