remove_device() and add_device() are not related to ACPI APIs, it does not make sense to return acpi_status for both functions. Current implementation of add_device() always AE_OK, thus the return value checking for add_device() always return false for ACPI_FAILURE(status). This patch makes add_device() to be void and remove the unnecessary return value checking. remove_proc_entry() won't fail, thus change remove_device() to be void. Signed-off-by:

Fix resource reclaim in below cases: 1. acerhdf_register_platform() does not properly handle platform_device_alloc() failure and platform_device_add() failure This patch adds error handing for acerhdf_register_platform(). 2. acerhdf_register_platform() return err with acerhdf_dev == NULL. as a result, acerhdf_unregister_platform() does not do resource reclaim in acerhdf_init() error path. This patch adds error handing for acerhdf_register_platform(), thus correct the error handing path in acerhdf_init(). goto out_err instead of err_unreg if acerhdf_register_platform() fail. 3. platform_device_del() should only used in error handling. Current implementation missed a platform_device_put() in acerhdf_exit. This patch fixes it by using platform_device_unregister() instead of platform_device_del() in acerhdf_unregister_platform.

In current implementation, store_ledd() does not return error if write_acpi_int fail. This patch fixes it by return -ENODEV if write_acpi_int fail. Signed-off-by:

According to the comments of write_acpi_int_ret(), write_acpi_int_ret() should return 0 if write is successful, -1 else. Thus if handle is NULL, the write does not happen, it should return -1. Signed-off-by:

In the case of no match ( hotk->model == END_MODEL ), the only posible case to return 0 is to have a Samsung P30 detected. This patch improves readability by moving related code after if/else clause to be inside if clause. Signed-off-by:

In the case of no match ( hotk->model == END_MODEL ), model sholud be kfreed before return AE_OK. This patch includes below fixes: 1. adds a missing kfree(model) before return AE_OK. 2. asus_hotk_get_info should return int, thus return 0 instead of AE_OK. Signed-off-by:

The driver now supports the Compal JHL90 (which I use) and it has some added features. The biggest novelties are a battery interface (power_supply) and a temperature and fan control interface (hmwon). It also adds a power-off feature to the backlight subsystem and it exports a few files that can enable/disable wake_on_XXX events. Much of the original code of the old features is still there, but I've changed some names to keep the naming more coherent with the added functionalities. (Sorry for the huge patch) Some technical stuff about the new driver: First of all, I'm not sure if the extra features also work on the other Compal boards. Currently they only get enabled if the DMI data indicates you are on a JHL90 board. Secondly, I've noticed a quirk in my fan controller. I have to re-send the wanted pwm-level to the controller every so often. If I don't do this, the fanspeed will slowly rise until after a couple of minutes it's at full speed. (Note that every normal userland application will probably update the pwm-level every so often anyway, based on temperature readings, so this might not be an issue in practice) If this turns out to be a problem with all the controllers, maybe we should implement a kernel timer and have the driver re-send the pwm level every XX seconds to make this transparent to userspace? (However, I couldn't immediately find a way to do this cleanly.) Additional information can be found in the source comments.

platform_device_unregister calls platform_device_del and platform_device_put, thus this change is logically equivalent to original code. I made this change because the documents in platform.c shows that: platform_device_del and platform_device_put must _only_ be externally called in error cases. All other usage is a bug.

If dell_new_hk_type is true, dell_legacy_wmi_keymap will point to a memory allocated in setup_new_hk_map(). In this case, the memory is not freed in current implementation. This patch fixes the leak by kfree(dell_wmi_keymap) if dell_new_hk_type is true. Signed-off-by:

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller must kfree the returned buffer if AE_OK is returned. The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER, and thus must check its return value before accessing or kfree() on the buffer. This patch adds return value checking for wmi_get_event_data() and adds a missing kfree(obj) in the end of wmi_notify_debug Signed-off-by:

Jiri Slaby authored
Stanse found that there are two NULL checks missing in ips_monitor. So check their value too and bail out appropriately if the allocation failed. While at it, add one more kfree to the fail path. It is not necessary now, but may be needed in the future when a new allocation is added. And for completeness. Also remove unneeded initialization of the variables. They are all set right after their declaration. Signed-off-by:

Jesse Barnes authored
Intel Core i3/5 platforms with integrated graphics support both CPU and GPU turbo mode. CPU turbo mode is opportunistic: the CPU will use any available power to increase core frequencies if thermal headroom is available. The GPU side is more manual however; the graphics driver must monitor GPU power and temperature and coordinate with a core thermal driver to take advantage of available thermal and power headroom in the package. The intelligent power sharing (IPS) driver is intended to coordinate this activity by monitoring MCP (multi-chip package) temperature and power, allowing the CPU and/or GPU to increase their power consumption, and thus performance, when possible. The goal is to maximize performance within a given platform's TDP (thermal design point). Signed-off-by:
