[PATCH 0/2] reset: Fix the behavior of optional reset

[Kishon Vijay Abraham I]

This series is a result of discussion in [1]

This series does not return NULL for optional resets so that the client
driver knows whether it had obtained a reset or not.

If it returns -ENODATA, that would mean reset controller is not
obtained. However the reset API's wil not abort or throw error and
handle gracefully if it's passed -ENODATA.

    devm_reset_control_get_optional()
  reset: Let reset API's handle gracefully if reset_ctl is -ENODATA
