== Precise SRU Justification ==

Current kernel FTBFS if power_supply is set as a module.  This has never
been an issue as its built-in into the kernel.  It fails with:

 "sysfs_create_link_nowarn" [drivers/power/power_supply.ko] undefined!"

as this symbol is not exported into modules.

== Fix ==

Upstream commit 93278d151e7bd35ccd0e083d7f2d8123cbaf36f8 fixes the build
failure.

== Impact ==

Impact shouldn't be very high.  Only users building the kernel from source
and setting this as a module.

== Test Case ==

Build the kernel, setting CONFIG_POWER_SUPPLY=m in the configuration.
