From 5405d0051f7ca820d1781d87baf4d730ff58f208 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 21 Aug 2019 21:08:59 +0200 Subject: posix-cpu-timers: Remove pointless return value check set_process_cpu_timer() checks already whether the clock id is valid. No point in checking the return value of the sample function. That allows to simplify the sample function later.
