CVE-2026-46255

Summary: CVE-2026-46255 affects the Linux kernel fsl-edma driver (dmaengine). The issue arises because clocks allocated/enabled with devm_clk_get_enabled() are automatically cleaned up, but fsl_edma_remove() explicitly disables them via fsl_disable_clocks(), causing warnings during driver removal...
