Subject: [PATCH 5/6] dmaengine: stm32: mark of_device_id table as maybe unused
Date: Fri, 20 Nov 2020 17:23:02 +0100 [thread overview]
Message-ID: <20201120162303.482126-5-krzk@kernel.org> (raw)
In-Reply-To: <20201120162303.482126-1-krzk@kernel.org>
The driver uses a second of_device_id table in the probe()
function by passing it to of_match_node(). This code will be a no-op
for compile testing (!CONFIG_OF on x86_64):
drivers/dma/stm32-dmamux.c:171:34: warning:
‘stm32_stm32dma_master_match’ defined but not used [-Wunused-const-variable=]
