From c66e72f1721a6dfd62aff01aa05f23b9d3dc6b6b Mon Sep 17 00:00:00 2001 From: Chunyan Zhang Date: Tue, 19 May 2020 11:00:36 +0800 Subject: [PATCH] clk: sprd: return correct type of value for _sprd_pll_recalc_rate [ Upstream commit c2f30986d418f26abefc2eec90ebf06716c970d2 ] The function _sprd_pll_recalc_rate() defines return value to unsigned long, but it would return a negative value when malloc fail, changing to return its parent_rate makes more sense, since if the callback .recalc_rate() is not set, the framework returns the parent_rate as well.
