[v11,04/12] Makefile.headersinst: cleanup input files

Commit Message

Nicolas Dichtel March 27, 2017, 12:20 p.m. UTC

After the last three 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 input-files3-name is genhdr-y.
