dmaengine: ti: drop of_match_ptr and mark of_device_id table as maybe unused
The driver can match only via the DT table so the main table should be always used and the of_match_ptr does not have any sense (this also allows ACPI matching via PRP0001, even though it is not relevant here). The secondary match of_device_id tables (passed to of_match_node) should be marked as maybe unused to fix compile testing (!CONFIG_OF on x86_64) warnings: drivers/dma/ti/dma-crossbar.c:125:34: warning: ‘ti_am335x_master_match’ defined but not used [-Wunused-const-variable=] drivers/dma/ti/dma-crossbar.c:22:34: warning: ‘ti_dma_xbar_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20201120162303.482126-6-krzk@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
