drivers: uio: Kconfig: add MMU dependancy for UIO
The User space I/O drivers are useful, only when user space meaningful (MMU must be enabled). So need let it depend on MMU, or can not pass compiling, the related error (allmodconfig for H8300): CC [M] drivers/uio/uio.o drivers/uio/uio.c: In function 'uio_mmap_physical': drivers/uio/uio.c:650:2: error: implicit declaration of function 'pgprot_noncached' [-Werror=implicit-function-declaration] drivers/uio/uio.c:650:20: error: incompatible types when assigning to type 'pgprot_t' from type 'int' Signed-off-by: Chen Gang <gang.chen@asianux.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
