kumquat-buildroot/package/neard/neard-fix-missing-linux-nfc-header.patch
Thomas Petazzoni 90de2b9d96 neard: fix missing nfc.h header 
We have a patch that allows neard to build even on toolchain using old
kernel headers that lack the nfc.h header. However, after the bump to
neard 0.9, this patch was not updated to take into account the two new
plugins that neard has added.

Fixes http://autobuild.buildroot.org/results/5eeb6f62cc0e654a536b6614dc51e8af4e301bb6/build-end.log

Raw Blame History

Add a private copy of <linux/nfc.h>
The addition of the <linux/nfc.h> header in the kernel sources is
moderately recent, and therefore, a number of toolchains don't have
this header.
As a workaround until all reasonable toolchains get this header
included, add a configure check in neard to test whether this header
is available or not, and if not, use our own private copy of it.
