[PATCH] staging: vt6655: srom.c: Remove some unused functions

Rickard Strandqvist
2014-12-21T18:00:19Z

Removes some functions that are not used anywhere:
SROMbAutoLoad() SROMvReadSubSysVenId() SROMvWriteEtherAddress()
SROMvWriteAllContents() SROMbIsRegBitsOff() SROMbIsRegBitsOn()
SROMvRegBitsOff() SROMvRegBitsOn()

This was partially found by using a static code analysis program called cppcheck.
