Subject: [PATCH] security: export security_kernel_load_data function
Date:   Tue, 17 Jul 2018 22:23:37 +0200
Message-Id: <20180717202355.2119407-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The firmware_loader can be built as a loadable module, which now
fails when CONFIG_SECURITY is enabled, because a call to the
security_kernel_load_data() function got added, and this is
not exported to modules:

ERROR: "security_kernel_load_data" [drivers/base/firmware_loader/firmware_class.ko] undefined!

Add an EXPORT_SYMBOL_GPL() to make it available here.

Fixes: 6e852651f28e ("firmware: add call to LSM hook before firmware sysfs fallback")
