Subject: [PATCH v3 03/20] crypto: Remove depends on HAS_DMA in case of platform dependency
Date: Tue, 17 Apr 2018 19:49:03 +0200	[thread overview]
Message-ID: <1523987360-18760-4-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1523987360-18760-1-git-send-email-geert@linux-m68k.org>

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.
