binding and unbinding UART on i.MX93 reveals bug in lpuart_dma_shutdown

I was trying to debug our Bluetooth connected with LPUART. This resulted in a stack trace when I tried to unbind and bind. This was in the 6.12 kernel.

I am providing a patch in case anyone is interested.

Suspected Software Defect

For some reason I don't see my patch. Hopefully my patch will go this time.

This is for the Linux-IMX kernel, https://github.com/nxp-imx/linux-imx.git
