      redhat: set defaults for RHEL 10.0 · b2f55c6d
      Jan Stancek authored
      
      JIRA: INTERNAL
      Upstream Status: RHEL only
      
      Now that we have forked from CentOS Stream, we need to switch the release number
      to use the zstream scheme and update our default disttag to match that used by
      the brew build environment for RHEL 10.0.

      Inside the probe function when pm_runtime_enable() is called,
      the PM core invokes a resume callback if the device Host1x is
      in a suspended state. As it can be seen in the logs above,
      this leads to host1x_intr_start() function call which is
      trying to acquire a mutex lock. But, the function
      host_intr_init() only gets called after the pm_runtime_enable()
      where mutex is initialised leading to the use of mutex
      prior to its initialisation.
      
      Fix this by moving the mutex initialisation prior to the runtime
      PM enablement function pm_runtime_enable() in probe.
