From 012ef70336a0dfb33ebe30cd80ec86aa1fe61f79 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Mon, 2 Jan 2017 14:06:59 -0300 Subject: [PATCH] crypto: picoxcell - Remove spacc_is_compatible() wrapper function The function is used to check either the platform device ID name or the OF node's compatible (depending how the device was registered) to know which device type was registered. But the driver is for a DT-only platform and so there's no need for this level of indirection since the devices can only be registered via OF.
