From mboxrd@z Thu Jan 1 00:00:00 1970 From: pure.logic@nexus-software.ie (Bryan O'Donoghue) Date: Mon, 1 Jan 2018 19:42:43 +0000 Subject: [PATCH v3 04/34] clk: omap2: change omap2_round_to_table_rate return logic In-Reply-To: <1514835793-1104-1-git-send-email-pure.logic@nexus-software.ie> References: <1514835793-1104-1-git-send-email-pure.logic@nexus-software.ie> Message-ID: <1514835793-1104-5-git-send-email-pure.logic@nexus-software.ie> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch updates the round_rate() logic here to return zero instead of a negative number on error. In conjunction with higher-level changes associated with acting on the return value of clk_ops->round_rate() it is then possible to have clk_ops->round_rate() return values from 1 Hz to ULONG_MAX Hz instead of the current limitation of 1 Hz to LONG_MAX Hz.
