Reduce object space ~2% using more current logging styles. Neaten and simplify logging macros. Use wiphy_<level> where appropriate. Coalesce formats. Convert ERROR/WARNING/INFO macros to rt2x00_<level> Convert EEPROM to rt2x00_eeprom_dbg Convert PROBE_ERROR to rt2x00_probe_err Convert DEBUG to rt2x00_dbg Convert EEPROM to rt2x00_eeprom_dbg $ size drivers/net/wireless/rt2x00/built-in.o* text data bss dec hex filename 245639 71696 69584 386919 5e767 drivers/net/wireless/rt2x00/built-in.o.new 240609 70096 68944 379649 5cb01 drivers/net/wireless/rt2x00/built-in.o.new.nodyndbg 240609 70096 68944 379649 5cb01 drivers/net/wireless/rt2x00/built-in.o.new.no_rt2x00_debug 249198 70096 70352 389646 5f20e drivers/net/wireless/rt2x00/built-in.o.old 249198 70096 70352 389646 5f20e drivers/net/wireless/rt2x00/built-in.o.old.nodyndbg 244222 70096 69712 384030 5dc1e drivers/net/wireless/rt2x00/built-in.o.old.no_rt2x00_debug Signed-off-by: Joe Perches <joe@perches.com> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.
