> Subject: [Intel-wired-lan] [PATCH iwl-net] ice: add missing xa_destroy
> for sched_node_ids
> 
> Commit 16dfa49406bc ("ice: Introduce new parameters in
> ice_sched_node") added a sched_node_ids xarray to the port info
> structure, but never called xa_destroy on it.
> 
> Since xarrays can allocate internal memory, this can result in a
> memory leak even if every element in the xarray has been removed.
> 
> Add a call to xa_destroy the structure during ice_deinit_hw(), and one
> to the unrolling cleanup path during errors in ice_init_hw(). While
> here, remove the overly verbose comment explaining the nature of the
> sched_node_ids xarray.
> 
> This was caught by Sashiko during development of unrelated code.

> Fixes: 16dfa49406bc ("ice: Introduce new parameters in
> ice_sched_node")
