Subject: [PATCH -next] serial: stm32: fix build failure
Date: Thu, 6 Oct 2016 11:33:33 +0200	[thread overview]
Message-ID: <1475746413-18301-1-git-send-email-alexandre.torgue@st.com> (raw)

While building m32r config the build failed with:
ERROR: stm32-usart.c:(.text+0xdc988): undefined reference to `bad_dma_ops'

To satisfy the dependency CONFIG_SERIAL_STM32 should depend on HAS_DMA.
