Subject: [PATCH 4.9 53/62] ARM: iop: dont use using 64-bit DMA masks
Date: Mon,  6 May 2019 16:33:24 +0200	[thread overview]
Message-ID: <20190506143055.916911177@linuxfoundation.org> (raw)
In-Reply-To: <20190506143051.102535767@linuxfoundation.org>

[ Upstream commit 2125801ccce19249708ca3245d48998e70569ab8 ]

clang warns about statically defined DMA masks from the DMA_BIT_MASK
macro with length 64:

 arch/arm/mach-iop13xx/setup.c:303:35: error: shift count >= width of type [-Werror,-Wshift-count-overflow]
 static u64 iop13xx_adma_dmamask = DMA_BIT_MASK(64);
                                  ^~~~~~~~~~~~~~~~
 include/linux/dma-mapping.h:141:54: note: expanded from macro 'DMA_BIT_MASK'
 #define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
                                                      ^ ~~~

The ones in iop shouldn't really be 64 bit masks, so changing them
to what the driver can support avoids the warning.
