[alsa-devel] [PATCH v2 5/7] Makefile.headersinst: cleanup input files

[Nicolas Dichtel]

After the last four patches, all exported headers are under uapi/, thus
input-files2 are not needed anymore.
The side effect is that input-files1-name is exactly header-y.

Note also that unput-files3-name is genhdr-y.
