ALSA: hda: hda_component: Add missing #include guards

rfvirgil · tiwai · commit 27219a5b3285 · 2024-03-07T17:27:39.000+01:00
Add the conventional include guards around the content of the
hda_component.h header file. This prevents double-declaration of
struct hda_component if the header gets included multiple times.

This isn't causing any problems with current code, so no need to
backport to older kernels.
