Hi Masahiro,
I'm wondering what is proper way to deal with such type of regressions?
Is is responsibility of person who change kconfig to check (and possibly
adjust) affected defconfigs?
A question for you as a kconfig expert :)

Subject: [PATCH] ARC: [plat-hsdk]: fix USB regression
As of today the CONFIG_USB isn't explicitly present in HSDK defconfig
as it is implicitly forcibly enabled by UDL driver which selects CONFIG_USB
in its kconfig.
The commit 5d50bd440bc2 ("drm/udl: Make udl driver depend on CONFIG_USB")
reverse the dependencies between UDL and USB so UDL now depends on
CONFIG_USB and not selects it. This introduces regression for ARC HSDK
board as HSDK defconfig wasn't adjusted and now it misses USB support
due to lack of CONFIG_USB enabled.
Fix that.
Fixes: 5d50bd440bc2 ("drm/udl: Make udl driver depend on CONFIG_USB")
