some messages take 4 bytes, but only fill 3 bytes.... this patch makes sure that whatever we send to the SCU is zeroed first Signed-off-by:

The stack buffer for IPC messages was 16 bytes, limiting messages to a size of 4 (each message is 32 bit). However, the touch screen driver is trying to send messages of size 5.... (AC: Set to 20 bytes having checked the max size allowed) Signed-off-by:

Moorestown has PMIC chip which contains GPIO blocks. The PMIC chip is connected to Langwell by SPI interface. So this GPIO driver will be regarded as SPI GPIO expander though the actual GPIO access is through IPC and SRAM. The SPI master contoller will probe this device driver by parsing SPIB table. Cleaned up for new IPC, GPE removed and some printk and other tidying by Alan Cox. Fixes for points noted by Matthew Garrett Signed-off-by:

Formerly these have been exposed through /proc/.. Better register them where all IO ports should get registered and scream loud if someone else claims to use them. EC data and command port typically should show up like this then: ... 0060-0060 : keyboard 0062-0062 : EC data 0064-0064 : keyboard 0066-0066 : EC command 0070-0071 : rtc0 ... Signed-off-by:

A userspace app to easily read/write the EC can be found here: ftp://ftp.suse.com/pub/people/trenn/sources/ec/ec_access.c Multiple ECs are not supported, but shouldn't be hard to add as soon as the ec driver itself will support them. Signed-off-by:

This patch provides the same information through debugfs, which previously was provided through /proc/acpi/embedded_controller/*/info This is the gpe the EC is connected to and whether the global lock gets used. The io ports used are added to /proc/ioports in another patch. Beside the fact that /proc/acpi is deprecated for quite some time, this info is not needed for applications and thus can be moved to debugfs instead of a public interface like /sys. Signed-off-by:

Other patches in this series add the same info to /sys/... and /proc/ioports. The info removed should never have been used in an application, eventually someone read it manually. /proc/acpi is deprecated for more than a year anyway... Signed-off-by:

In current implementation, acpi_pcc_write_sset return 1 if write is successful, 0 if write is failed. But all the callers consider acpi_pcc_write_sset return 0 if write is successful and return negtive if write is failed. This patch changes the implementation of acpi_pcc_write_sset to return 0 if write is successful, -EIO if write is failed. Signed-off-by:

The hotplug_disabled module parameter is determinated at the module load time. Change the value after the module is loaded does not make sense and has no effect at all, thus set the permissions to 0444 instead of 0644. Signed-off-by:

The wapf module parameters defines the behavior of the Fn+Fx wlan key. The wlan_status and bluetooth_status module parameters are for setting the wlan/bluetooth status on boot. All above module parameters are determinated only at the module load time. Change the value after the module is loaded does not make sense and has no effect at all, thus set the permissions to 0444 instead of 0644. Signed-off-by:

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER, the caller must kfree the returned buffer if AE_OK is returned. Call Trace: wmab_execute -> wmi_evaluate_method -> acpi_evaluate_object Thus if callers of wmab_execute() pass ACPI_ALLOCATE_BUFFER, the return buffer must be kfreed if wmab_execute return AE_OK.

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_query_block() pass ACPI_ALLOCATE_BUFFER, and thus must check its return value before accessing or kfree() on the buffer. This patch adds a missing kfree(out.pointer) before exit WMID_set_capabilities() and get_wmid_devices(). Signed-off-by:

Add error checking and return -ENOMEM if input_allocate_device() fail. Signed-off-by:

Axel Lin authored
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.
