Subject: [PATCH v2 15/21] net: Remove depends on HAS_DMA in case of platform dependency
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.
Note:
- FSL_FMAN keeps its dependency on HAS_DMA, as it calls set_dma_ops().
set_dma_ops() does not exist if NO_DMA=y, and its use in this driver
is questionable.
