Subject: [PATCH 0/2] cpufreq: qcom: Clock provider fixes

Hi,

This series has a couple of fixes for the Qcom CPUFreq clock provider.
Patch 1 fixes an issue where incorrect rate might be reported if LMh IRQ is not
available for a platform (issue identified based on code inspection). Patch 2
fixes a regression reported for v6.13-rc1 [1]. The regression was triggered by
commit 25f1c96a0e84 ("clk: Fix invalid execution of clk_set_rate"), which fixed
the behavior of the clk_set_rate() API. Even though the commit got reverted now,
patch 2 fixes the issue in the clock provider code.

This series is tested on Qcom RB5 development board.
