sysfs: Introduce DEFINE_SIMPLE_SYSFS_GROUP_VISIBLE()
One of the first users of DEFINE_SYSFS_GROUP_VISIBLE() did this:
static umode_t dp0_attr_visible(struct kobject *kobj,
struct attribute *attr,
int n)
{
struct sdw_slave *slave = dev_to_sdw_dev(kobj_to_dev(kobj));
if (slave->prop.dp0_prop)
return attr->mode;
return 0;
}
static bool dp0_group_visible(struct kobject *kobj)
{
struct sdw_slave *slave = dev_to_sdw_dev(kobj_to_dev(kobj));
if (slave->prop.dp0_prop)
return true;
return false;
}
DEFINE_SYSFS_GROUP_VISIBLE(dp0);
...i.e. the _group_visible() helper is identical to the _attr_visible()
helper. Use the "simple" helper to reduce that to:
static bool dp0_group_visible(struct kobject *kobj)
{
struct sdw_slave *slave = dev_to_sdw_dev(kobj_to_dev(kobj));
if (slave->prop.dp0_prop)
return true;
return false;
}
DEFINE_SIMPLE_SYSFS_GROUP_VISIBLE(dp0);
Remove the need to specify per attribute visibility if the goal is to
hide the entire group.
