Hi Ben, Andrew Morton is reporting scx200_acb compilation breakage on non-x86 due to the use of asm/msr.h, which only i386 and x86_64 have. This is caused by your patch adding CS5535 support. Now, how do we fix the problem? First solution is to make the driver depend on X86. But are there other architectures where this driver may be used? I'd guess not. Second solution is to surround the CS5535 specific parts with #ifdef X86 so that the driver can still be compiled on other architectures. Opinions? Thanks, -- Jean Delvare
