This thing is completely broken and causes a lot of nasty error
messages on 64-bit:
drivers/dma/sun4i-dma.c: In function ‘find_and_use_pchan’:
drivers/dma/sun4i-dma.c:241:32: warning: passing argument 1 of
‘find_next_zero_bit’ from incompatible pointer type
[-Wincompatible-pointer-types]
...
and this needs to be fixed.
I've removed the COMPILE_TEST option for that config in the meantime,
because I refuse to have my screen fill up with warnings like this.
COMPILE_TEST is fine for drivers that are supposed to compile cleanly
even if they might not work - and encouraging people to _keep_ them
compiling cleanly and get better compile test coverage.
But it's not fine for stuff that causes big warnings and might hide
actual real problems.
