net: wan: add missing virt_to_bus dependencies (303c28d8) · Commits · 戴 / test

The cosa driver is rather outdated and does not get built on most platforms because it requires the ISA_DMA_API symbol. However there are some ARM platforms that have ISA_DMA_API but no virt_to_bus, and they get this build error when enabling the ltpc driver. drivers/net/wan/cosa.c: In function 'tx_interrupt': drivers/net/wan/cosa.c:1768:3: error: implicit declaration of function 'virt_to_bus' unsigned long addr = virt_to_bus(cosa->txbuf); ^ The same problem exists for the Hostess SV-11 and Sealevel Systems 4021 drivers. This adds another dependency in Kconfig to avoid that configuration. Signed-off-by:
