If you say yes here, you get support for JEDEC JC42.4 compliant
temperature sensors, which are used on many DDR3 memory modules for
mobile devices and servers. Support will include, but not be limited
to, ADT7408, CAT34TS02, CAT6095, MAX6604, MCP9805, MCP98242, MCP98243,
MCP9843, SE97, SE98, STTS424(E), TSE2002B3, and TS3000B3.

This driver can also be built as a module. If so, the module
will be called jc42.
