AI-suggested

A fix is available that initializes the early_pmc->rate variable properly. Users should apply the updated Linux kernel versions containing this fix to resolve the issue.

Description

A vulnerability in the Linux kernel's Tegra PMC driver caused the early_pmc->rate variable to remain uninitialized for legacy 32-bit Tegra devices, triggering warnings and potentially affecting power management suspend mode. This issue arose after the PMC driver was updated to create the PMC context dynamically but missed initializing the rate in the early PMC context. The flaw has been fixed by properly initializing the early_pmc->rate variable.
