CVE-2026-46255

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: fsl-edma: don't explicitly disable clocks in .remove()

The clocks in fsl_edma_engine::muxclk are allocated and enabled with devm_clk_get_enabled(), which automatically cleans these resources up, but these clocks are also manually disabled in fsl_edma_remove(). This causes warnings on driver removal for each clock:

    edma_module already disabled

Fix these warnings by removing the unnecessary fsl_disable_clocks() call in fsl_edma_remove().
