That's interesting. I did a grep over all 16944 GPL licensed files with an SPDX
identifier.

785 of them have a license text while 16159 don't. I will remove mine.

When stripping off aspeed_edac_, some static function names will become quite
"bare-bone":

aspeed_edac_init(), aspeed_edac_exit(), aspeed_edac_probe(),
aspeed_edac_remove(), aspeed_edac_of_match(), aspeed_edac_isr(),
aspeed_edac_config_irq().


Does your suggestion also apply to static variables? E.g. aspeed_edac_regmap,
aspeed_edac_regmap_config, aspeed_edac_driver? Also, here some variable names
would become quite "bare-bone".
