When CONFIG_I2C=m, CONFIG_I2C_SLAVE=y (bool), and CONFIG_IPMI_IPMB=y,
the build fails with:
ld: drivers/char/ipmi/ipmi_ipmb.o: in function `ipmi_ipmb_remove':
ipmi_ipmb.c:(.text+0x6b): undefined reference to `i2c_slave_unregister'
ld: drivers/char/ipmi/ipmi_ipmb.o: in function `ipmi_ipmb_thread':
ipmi_ipmb.c:(.text+0x2a4): undefined reference to `i2c_transfer'
ld: drivers/char/ipmi/ipmi_ipmb.o: in function `ipmi_ipmb_probe':
ipmi_ipmb.c:(.text+0x646): undefined reference to `i2c_slave_register'
ld: drivers/char/ipmi/ipmi_ipmb.o: in function `ipmi_ipmb_driver_init':
ipmi_ipmb.c:(.init.text+0xa): undefined reference to `i2c_register_driver'
ld: drivers/char/ipmi/ipmi_ipmb.o: in function `ipmi_ipmb_driver_exit':
ipmi_ipmb.c:(.exit.text+0x8): undefined reference to `i2c_del_driver'
This is due to having a tristate depending on a bool symbol.
By adding I2C (tristate) as a dependency, the desired dependencies
are met, causing IPMI_IPMB to be changed from =y to =m:
-CONFIG_IPMI_IPMB=y
+CONFIG_IPMI_IPMB=m

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
