If there is an internal "no-memory" output from inside kmemdup now, I guess the one in the clock driver would be a duplicate and could go away. > * Is there a need to adjust the error handling here? There is no need for additional error handling. Like if the rate-table could not be duplicated, the clock will still report the correct clockrate you can just not set a new rate. And for a system it's always better to have the clock driver present than for all device-drivers to fail probing. Especially as this start as core clock driver, so there is no deferring possible.
