From 2a7f51a3e08cdaeea78d9e101a0079422a55bbc3 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 21 Jan 2012 09:28:53 +0000 Subject: [PATCH] MFD: mcp-core: fix mcp_priv() to be more type safe mcp_priv() does unexpected things when passed a void pointer. Make it a typed inline function, which ensures that it works correctly in these cases.
