6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peng Fan <peng.fan@xxxxxxx>
commit f7c7c5aa556378a2c8da72c1f7f238b6648f95fb upstream.
The check condition should be 'i < bc->onecell_data.num_domains', not
'bc->onecell_data.num_domains' which will make the look never finish
and cause kernel panic.
Also disable runtime to address
"imx93-blk-ctrl 4ac10000.system-controller: Unbalanced pm_runtime_enable!"
Fixes: e9aa77d413c9 ("soc: imx: add i.MX93 media blk ctrl driver")
