G_TYPE_INSTANCE_GET_PRIVATE has been deprecated since glib version
2.58 and should be replaced with the xxx_get_instance_private (obj)
which is generated by G_ADD_PRIVATE.
Use G_DEFINE_TYPE_WITH_CODE (..., G_PRIVATE_ADD (...)) instead of
the (deprecated since glib 2.58) function g_type_class_add_private
to add a private structure for a type.
Bump the minimal required version of glib to 2.38.0, the version
where G_PRIVATE_ADD was added.
Fix double-close on exit. If we created a GIOChannel from the file
descriptor, then g_io_channel_shutdown() will close that file descriptor
as well. Close the channel first, so that the file descriptor is only
closed manually if we didn't manage to create a GIOChannel from it.

In up_input_coldplug(), some checks are done on the input device found in order
to detect if it's a lid switch or not.
The following one is problematic :
/* convert to a bitmask */
num_bits = up_input_str_to_bitmask (contents, bitmask, sizeof (bitmask));
if (num_bits != 1) {
g_debug ("not one bitmask entry for %s", native_path);
ret = FALSE;
goto out;
}
Checking if there's only 1 bit set is wrong. It's nice if you have a x86 with
acpi using 1 input device for the lid switch but it's not always nice.
One can create input devices with gpios-keys like this:
static struct gpio_keys_button keys[] = {
{
.code = SW_LID,
.gpio = ...,
.type = EV_SW,
.desc = "Lid Switch",
},
{
.code = SW_RFKILL_ALL,
.gpio = ...,
.type = EV_SW,
.desc = "rfkill",
},
};
The resulting SW bitmap will be 9 and thus there are 2 bits sets and due to the
mentionned check, the device is ignored by upower.
As a fix, I'm checking if the number of bits is between 0 and SW_CNT
bits.
