staging: Comedi: comedi_fops: Fixed the return error code
This patch fixes the checkpatch.pl warning: WARNING: ENOSYS means 'invalid syscall nr' and nothing else try_module_get fails when the reference count of the module is not allowed to be incremented ,and hence -ENXIO is returned indicating no device or address. [IA - combined two of santhosh's changes to the error return value!] Signed-off-by: santhosh pai <santhosh.pai88@yahoo.com> Reviewed-by: Ian Abbott <abbotti@mev.co.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
