[PATCH] sound: core: Add SPDX license id to files

Tim Bird
2026-02-12T18:31:23Z

Add an SPDX id of LGPL-2.0+ to files in the
sound core sub-system that are missing ids. Remove
boilerplate text.

These files were originally submitted in a big commit
for the ALSA sound system for kernel version 2.5.4,
by Jaroslav Kysela, in Feb 2002.
