Hi Samuel, After merging the mfd tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/built-in.o: In function `i2c_block_write': stmpe-i2c.c:(.text+0xf4553): undefined reference to `i2c_smbus_write_i2c_block_data' drivers/built-in.o: In function `i2c_block_read': stmpe-i2c.c:(.text+0xf457f): undefined reference to `i2c_smbus_read_i2c_block_data' drivers/built-in.o: In function `i2c_reg_write': stmpe-i2c.c:(.text+0xf45ab): undefined reference to `i2c_smbus_write_byte_data' drivers/built-in.o: In function `i2c_reg_read': stmpe-i2c.c:(.text+0xf45d4): undefined reference to `i2c_smbus_read_byte_data' drivers/built-in.o: In function `stmpe_init': stmpe-i2c.c:(.init.text+0xaf22): undefined reference to `i2c_register_driver' drivers/built-in.o: In function `stmpe_exit': stmpe-i2c.c:(.exit.text+0x5e5): undefined reference to `i2c_del_driver' Caused by commit b25a31a3b4d3 ("mfd: Separate out STMPE controller and interface specific code"). I have used the mfd tree from next-20111219 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx http://www.canb.auug.org.au/~sfr/
