0096-kernel-remove-packaging-of-kmod-crypto-core-and-kmod-crypto-arc4.patch

From: Matthias Schiffer <mschiffer@universe-factory.net>
Date: Thu, 16 Jun 2016 03:42:03 +0200
Subject: kernel: remove packaging of kmod-crypto-core and kmod-crypto-arc4

Everything except for blkcipher was already built-in, so make blkcipher
built-in as well.

Signed-off-by: Felix Fietkau <nbd@openwrt.org>

Backport of OpenWrt r46820

The packages kmod-crypto-{core,arc4} are added to kernel PROVIDES to
satisfy dependencies of CC packages.
