Subject: serial: SERIAL_STM32 should depend on HAS_DMA
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc2a024f865d712bb5748aabe77cd515d7d5eea9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

serial: SERIAL_STM32 should depend on HAS_DMA

If NO_DMA=y:

    drivers/built-in.o: In function `stm32_serial_remove':
    stm32-usart.c:(.text+0xcea1a): undefined reference to `bad_dma_ops'
    stm32-usart.c:(.text+0xcea7a): undefined reference to `bad_dma_ops'

Add a dependency on HAS_DMA to fix this.
