Error in compiling a Linux kernel

How do you read the errors?

I run after having .config -file at /home/aal/build/kernel.

/usr/src/linux-2.6$ make O=/home/aal/build/kernel/

I get

  ... cut ...

The errors are in a staging driver, i.e. either not yet, or already not stable driver (take a look e.g. here for a discussion of the staging tree.) You can disable these in kernel config Device Drivers --> Staging Drivers.
