[PATCH 5.10 152/459] ALSA: usx2y: Fix spaces

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 4c0a58ef36f3de1be0d1c8565ca854bcabd37e2b ]

This patch corrects merely the spaces in the usx2y code, including the
superfluous trailing space in the debug prints and a slight reformat
of some comment lines.  Nothing really touches about the code itself.
