From bef59c5024be687ef4f228915af9961307a779ab Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Wed, 20 Aug 2014 15:26:35 +0200 Subject: devres: Improve devm_kasprintf()/kvasprintf() support - Add devm_kasprintf()/kvasprintf(), introduced by commit 75f2a4ead5d5890ada9c2663a70fb58613c0d9f2 ("devres: Add devm_kasprintf and devm_kvasprintf API"), to Documentation/driver-model/devres.txt, - Improve kernel doc: the string is not an existing formatted string, but is formatted into the newly-allocated buffer, - Add a __printf() annotation to devm_kasprintf(), so the compiler will verify the format string argument types.
