gcc-7.0.1 warns about old code in ttpci: In file included from drivers/media/pci/ttpci/av7110.c:63:0: In function 'irdebi.isra.2', inlined from 'start_debi_dma' at drivers/media/pci/ttpci/av7110.c:376:3, inlined from 'gpioirq' at drivers/media/pci/ttpci/av7110.c:659:3: drivers/media/pci/ttpci/av7110_hw.h:406:3: warning: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=] memcpy(av7110->debi_virt, (char *) &res, count); In function 'irdebi.isra.2', inlined from 'start_debi_dma' at drivers/media/pci/ttpci/av7110.c:376:3, inlined from 'gpioirq' at drivers/media/pci/ttpci/av7110.c:668:3: drivers/media/pci/ttpci/av7110_hw.h:406:3: warning: 'memcpy': specified size between 18446744071562067968 and 18446744073709551615 exceeds maximum object size 9223372036854775807 [-Wstringop-overflow=] memcpy(av7110->debi_virt, (char *) &res, count); Apparently, 'count' can be negative here, which will then get turned into a giant size argument for memcpy. Changing the sizes to 'unsigned int' instead seems safe as we already check for maximum sizes, and it also simplifies the code a bit.
