2008-06-10power_supply: Fix race in power_supply_ueventDmitry Baryshkov1-1/+1
Commit 54d29ad33e3483bcc7ca433a21cf294854e5154a (Power Supply: fix race in device_create) introduced a race in power_supply_uevent. Previously it checked that power_supply is available by checking for dev->driver_data. But now dev->driver_data is set before power_supply->dev is initialised.

2008-05-21Power Supply: fix race in device_createGreg Kroah-Hartman1-4/+2
There is a race from when a device is created with device_create() and then the drvdata is set with a call to dev_set_drvdata() in which a sysfs file could be open, yet the drvdata will be NULL, causing all sorts of bad things to happen. This patch fixes the problem by using the new function, device_create_drvdata().

2008-04-29x86: olpc: add One Laptop Per Child architecture supportAndres Salomon1-2/+0
This adds support for OLPC XO hardware. Open Firmware on XOs don't contain the VSA, so it is necessary to emulate the PCI BARs in the kernel. This also adds functionality for running EC commands, and a CONFIG_OLPC. A number of OLPC drivers depend upon CONFIG_OLPC. olpc_ec_timeout is a hack to work around Embedded Controller bugs.

2008-02-07power_supply: remove capacity_level from list of sysfs attributesThadeu Lima de Souza Cascardo1-1/+0
This commit: commit 8efe444038a205e79b38b7ad03878824901849a8 Author: Andres Salomon <dilinger@queued.net> Date: Wed Dec 12 14:12:56 2007 -0500 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.

2008-02-02power: fix incorrect unregistration in power_supply_create_attrs error pathAndres Salomon1-4/+2
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.

2008-02-02power: remove POWER_SUPPLY_PROP_CAPACITY_LEVELAndres Salomon2-15/+0
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.

2007-10-13Driver core: change add_uevent_var to use a structKay Sievers2-14/+6
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.

2007-07-15pda_power: clean up irq, timerJeff Garzik1-9/+8
Clean up pda_power interrupt handling: Prior to this patch, the driver would pass information it needed to the interrupt handler dev_id pointer, and then prompt forget it ever did so, recreating that same information after a couple passes through the timer-based state machine. This patch removes the redundant checks by passing the pda_power_supply[] pointer through the state machine. The current code passed 'irq' through the state machine, as an index to recreate the pointer, when we could more simply pass around the pointer itself. This patch makes it easier to remove the 'irq' argument in the future, in addition to cleaning up the driver today. Signed-off-by: Jeff Garzik <jeff@garzik.org>
