Subject[PATCH v2 3/4] drivers: clk: zynqmp: Fix invalid clock name queries
Date
From: Rajan Vaja <rajan.vaja@xilinx.com>

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 zynqmp_pm_clock_get_name() in versal_get_clock_info() function.
