Hi All, I am trying to make stack for my learning in which i made a bus driver and
device driver when i am trying to create device sysfs file after registering it with the
bus i am getting oops after some digging i found that the compiler is reporting warning
for using preprocessor macro called DEV_ATT. code is as follows. can anybody help me to
remove this warning. static ssize_t show_host_device_version(struct device *ddev, char
*buf){ struct HOST *dev = ddev->driver_data; return print_dev_t(buf,
dev->cdev.dev);}static
DEVICE_ATTR(host_device_version,S_IRUGO,show_host_device_version,NULL);
device_create_file(&dev->host.dev, &dev_attr_host_device_version); Regards
