From 65bcca9f52af8ff88d46de317a9ca6e8a2da5d69 Mon Sep 17 00:00:00 2001 From: Rajan Vaja Date: Thu, 16 Jan 2020 03:55:05 -0800 Subject: [PATCH] versal: drivers: clk: Fix invalid clock name queries The clock driver makes EEMI call to get the name of invalid clk when executing versal_get_clock_info() function. This results in error messages. Added check for validating clock before saving clock attribute and calling versal_pm_clock_get_name() in versal_get_clock_info() function.
