Hi Stephen, Thanks a lot for your help. I fix it now. Please help to review it. It's already passed the build test.

The 88pm8607 patch is just for mfd-2.6 git tree. I didn't try it in linux-next git tree before. I can try it now. If I could have your .config file, it would be better. I am sorry, but I don't have the exact .config file any more (I have moved on in my creation of linux-next) however, as I said, this was an allmodconfig build on x86_64. I also noted that CONFIG_I2C=m and CONFIG_MFD_CORE=m, while the config entry that controls the building of this driver is a bool so must have been 'y'. So from a builtin driver, you are referring to symbols that are only defined in modules. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
