Subject: eeprom: at24: Use dev_err_probe for nvmem register failure
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a3c10035d12f5ec10915d5c00c2e8f7d7c066182;p=linux.git

eeprom: at24: Use dev_err_probe for nvmem register failure

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.
