From 4e2afeb9e653d4201039f06c02a37312bc38c3b8 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Mon, 6 Jun 2016 18:00:27 +0200 Subject: [PATCH] clocksource/drivers/time-lpc32xx: Convert init function to return error The init functions do not return any error. They behave as the following: - panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly or - print an error and let the caller unaware if the state of the system Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype. Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function.
