Hi,
When trying to test my coresight patches, I found that etr,etf and stm device nodes are missing from /dev.
Bisection gives this as the bad commit.
1be01d4a57142ded23bdb9e0c8d9369e693b26cc is the first bad commit commit 1be01d4a57142ded23bdb9e0c8d9369e693b26cc Author: Geert Uytterhoeven <geert+renesas@glider.be> Date: Thu Mar 14 12:13:50 2019 +0100
driver: base: Disable CONFIG_UEVENT_HELPER by default
Since commit 7934779a69f1184f ("Driver-Core: disable /sbin/hotplug by default"), the help text for the /sbin/hotplug fork-bomb says "This should not be used today [...] creates a high system load, or [...] out-of-memory situations during bootup". The rationale for this was that no recent mainstream system used this anymore (in 2010!).
A few years later, the complete uevent helper support was made optional in commit 86d56134f1b67d0c ("kobject: Make support for uevent_helper optional."). However, if was still left enabled by default, to support ancient userland.
Time passed by, and nothing should use this anymore, so it can be disabled by default.

Any idea on this?
