The option BR2_LINUX_KERNEL_PATCH can contain just the directory name,
and this directory does not have any naming requirement.

The patches themselves should be named linux-something.patch. In your
original mail you wrote Linux-something.patch, with a capital L which
is not correct.

What you're supposed to see is something like:
>>> linux 3.16.1 Patching
for p in /tmp/foo/ ; do if echo $p | grep -q -E "^ftp://|^http://" ;
then support/scripts/apply-patches.sh
/home/tdescham/repo/contrib/buildroot-review/output/build/linux-3.16.1
/home/tdescham/repo/contrib/dl `basename $p` ; elif test -d $p ; then
support/scripts/apply-patches.sh
/home/tdescham/repo/contrib/buildroot-review/output/build/linux-3.16.1
$p linux-\*.patch ; else support/scripts/apply-patches.sh
/home/tdescham/repo/contrib/buildroot-review/output/build/linux-3.16.1
`dirname $p` `basename $p` ; fi done

Applying linux-bar.patch using patch:


In this example, I had:
BR2_LINUX_KERNEL_PATCH="/tmp/foo/"

and
$ find /tmp/foo
/tmp/foo
/tmp/foo/Linux-baz.patch
/tmp/foo/linux-bar.patch

Best regards,
Thomas
