Just to be crystal clear -- could you share the outputs for dev info:
 - before update
 - after update, before reboot/reload
 - after update, after activation (/reboot/reload)
?

AFAICT the code is fine but talking about the "inactive versions"
is not exactly in line with the uAPI expectations.

Don't call functions which need error checking as part of variable init.

This function would benefit from having ctx->dev_caps.common_cap
stored to a local variable with a shorter name :S
