Thadeu Lima de Souza Cascardo 4cbc76eadf power_supply: remove capacity_level from list of sysfs attributes
This commit:

commit 8efe444038
Author: Andres Salomon <dilinger@queued.net>

    power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL

Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs
attributes with one more entry than the number of enums in power_supply.h.
This leads to some attributes containing the value of the attribute right
after it.  For example, temp_ambient would have the value of
time_to_empty_now.  In my case, I had time_to_full_avg have the value which
should be in model_name, when the former was usually empty.

serial number can tell you from the imminent danger

Andres Salomon 839dc9f105 power: fix incorrect unregistration in power_supply_create_attrs error path
In power_supply_create_attrs(), we create static attributes as referenced
by power_supply_static_attrs[i].  After that, if we fail, we unregister
via power_supply_static_attrs[psy->properties[i]].  This is incorrect, as
psy->properties has absolutely no bearing on static attribs.  This patch
fixes it to unregister the correct attrib.

Another line which was unnecessarily line wrapped is also unwrapped.

Andres Salomon 8efe444038 power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL
The CAPACITY_LEVEL stuff defines various levels of charge; however, what
is the difference between them?  What differentiates between HIGH and NORMAL,
LOW and CRITICAL, etc?

As it appears that these are fairly arbitrary, we end up making such policy
decisions in the kernel (or in hardware).  This is the sort of decision that
should be made in userspace, not in the kernel.

If the hardware does not support _CAPACITY and it cannot be easily calculated,
then perhaps the driver should register a custom CAPACITY_LEVEL attribute;
however, userspace should not become accustomed to looking for such a thing,
and we should certainly not encourage drivers to provide CAPACITY_LEVEL
stubs.

The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL.  The
OLPC battery driver is the only driver making use of this, so it's
removed from there as well.

Kay Sievers 7eff2e7a8b Driver core: change add_uevent_var to use a struct
This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.
