3.6-stable review patch. If anyone has any objections, please let me know.
------------------ From: Paul Gortmaker <[email protected]> commit de0a41484c47d783dd4d442914815076aa2caac2 upstream. There is the seldom used corner case where HWMON=m at the same time as TIGON3=y (typically randconfigs) which will cause a link fail like: drivers/built-in.o: In function `tg3_close': tg3.c:(.text+0x16bd86): undefined reference to `hwmon_device_unregister' drivers/built-in.o: In function `tg3_hwmon_open': tg3.c:(.text+0x16fc4b): undefined reference to `hwmon_device_register' make[1]: *** [vmlinux] Error 1 Fix it as suggested by DaveM[1] by having the Kconfig logic simply select HWMON when TIGON3 is selected. This gets rid of all the extra IS_ENABLED ifdeffery in tg3.c as a side benefit.
