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

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

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

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

    edma_module already disabled
    WARNING: CPU: 0 PID: 418 at drivers/clk/clk.c:1200 clk_core_disable+0x198/0x1c8
    [...]
    Call trace:
     clk_core_disable+0x198/0x1c8 (P)

    edma_module already unprepared

     [...]
    ---[ end trace 0000000000000000 ]---

Fix these warnings by removing the unnecessary fsldisableclocks() call in fsledmaremove().
