5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Stein <alexander.stein@xxxxxxxxxxxxxxx>
[ Upstream commit a3c10035d12f5ec10915d5c00c2e8f7d7c066182 ]
When using nvmem layouts it is possible devm_nvmem_register returns
-EPROBE_DEFER, resulting in an 'empty' in
/sys/kernel/debug/devices_deferred. Use dev_err_probe for providing
additional information.
