From 9e578f6340ba3f4324cd823872afe6eda39857d2 Mon Sep 17 00:00:00 2001 From: Giulio Benetti Date: Sun, 14 Feb 2021 03:17:18 +0100 Subject: [PATCH] clk: fix clk_get_rate() documentation Improve clk_get_rate() @return documentation that otherwise is a bit ambiguous. At the moment I expect to return 0 as error since the return type is 'ulong', instead the function really returns negative value in case the corresponding function pointer is null and returns 0 if the clock is invalid.
