From 1df7338ac96558d5ae4c1a9dd5d1cb60fcd1bdb2 Mon Sep 17 00:00:00 2001 From: Sergey Senozhatsky Date: Fri, 10 Nov 2017 08:48:30 +0900 Subject: checkpatch: add pF/pf deprecation warning We deprecated '%pF/%pf' printk specifiers, since '%pS/%ps' is now smart enough to handle function pointer dereference on platforms where such dereference is required.
