Subject: serial: SERIAL_IMX_AUART should depend on HAS_DMA
X-Git-Tag: rel_imx_4.19.35_1.1.0~15706^2~42
X-Git-Url: https://git.somdevices.com/?a=commitdiff_plain;h=f8032cb4f574c0de5ac1d65d61e972957e6f1631;p=linux.git

serial: SERIAL_IMX_AUART should depend on HAS_DMA

If NO_DMA=y:

    ERROR: "dma_unmap_sg" [drivers/tty/serial/imx.ko] undefined!
    ERROR: "dma_map_sg" [drivers/tty/serial/imx.ko] undefined!

Add a dependency on HAS_DMA to fix this.
