5.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@xxxxxxx> [ Upstream commit 2ac7a12ead2be2e31bd5e796455bef31e8516845 ] Minor code refactoring by merging the superfluous function calls. The functions were split in the past for covering pre-history USB driver code, but this is utterly useless.
