From 12f2639038ef420fe796171ffb810b30d1ac0619 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 5 Apr 2019 21:46:12 +0200 Subject: tracing: stop making gpio tracing configurable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gpio tracing was made configurable in 4.4-rc1 (commit ddd70280bf0e ("tracing: gpio: Add Kconfig option for enabling/disabling trace events")). Since then it is the only event type that can be compiled conditionally. Given that there is only little overhead I don't understand the reasoning and I was annoyed more than once that gpio events were not available without recompiling. So drop the Kconfig symbol and make gpio events available unconditionally.
