Subject: [PATCH] serial: SERIAL_STM32 should depend on HAS_DMA
Date: Thu, 6 Oct 2016 15:55:24 +0200 [thread overview]
Message-ID: <1475762124-16609-1-git-send-email-geert@linux-m68k.org> (raw)
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.
