Subject: Help with compiler warning
Date: Thu, 21 Aug 2008 20:36:02 -0500	[thread overview]
Message-ID: <48AE1802.5090301@lwfinger.net> (raw)

In drivers/pcmcia/cardbus.c, the following statement

         memcpy_fromio(ptr, s->cb_cis_virt + addr, len);

generates the warning

   CC [M]  drivers/pcmcia/cardbus.o
include/asm/io_32.h: In function ‘memcpy_fromio’:
include/asm/io_32.h:151: warning: passing argument 2 of ‘__memcpy’ 
discards qualifiers from pointer target type

s->cb_cis_virt is "void __iomem" and addr is uint.

What cast does argument 2 need to silence the warning?

Thanks,

Larry
