[PATCH v4 1/9] pseries/plpks: fix double conversion of write and remove flush errors

[sashiko-bot at kernel.org]

> plpks_confirm_object_flushed() returns zero or a negative Linux errno.
> However, plpks_write_var() and plpks_remove_var() pass this return value
> through pseries_status_to_err(), which treats it as a raw hypervisor status
> and converts it again.
> 
> Convert only errors returned by the write and remove HCALLs, and propagate
> errors from plpks_confirm_object_flushed() unchanged.
> 
> Fixes: 2454a7af0f2a ("powerpc/pseries: define driver for Platform KeyStore")
> Cc: stable at vger.kernel.org # 6.0
