Hi Stephen,

Could you send your .config file to me? 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.

Thanks
Haojian

Hi Samuel,

Today's linux-next build (x86_64 allmodconfig) failed like this:

drivers/built-in.o: In function `pm8607_write_device':
88pm8607.c:(.text+0xd02e9): undefined reference to `i2c_master_send'
drivers/built-in.o: In function `pm8607_read_device':
88pm8607.c:(.text+0xd033b): undefined reference to `i2c_master_send'
88pm8607.c:(.text+0xd035c): undefined reference to `i2c_master_recv'

drivers/built-in.o: In function `pm8607_remove':
88pm8607.c:(.devexit.text+0x198): undefined reference to `mfd_remove_devices'

Obviously caused by commit 9ec6cd8f2235ddeee5b39068956f14238a12a617
("mfd: Add 88PM8607 driver").

This build has CONFIG_I2C=m and CONFIG_MFD_CORE=m.

I have used the version of the mfd tree form next-20091005 for today.
