* acerhdf: Clean up includesJean Delvare2011-05-27
| | | | | | | | | | | | | | | * The acerhdf driver isn't an ACPI driver, so it needs not include <acpi/acpi_drivers.h>. All it uses is ec_read() and ec_write(), for which <linux/acpi.h> is sufficient. * I couldn't find any reason why <linux/fs.h> and <linux/sched.h> were included. This should avoid unneeded rebuilds of the acerhdf driver.

* acerhdf: fix resource reclaim in error pathAxel Lin2010-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* acerhdf: limit modalias matching to supportedStefan Bader2009-12-24
| | | | | | | | | | | | | | | | | BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958 The module alias currently matches any Acer computer but when loaded the BIOS checks will only succeed on Aspire One models. This causes a invalid BIOS warning for all other models (seen on Aspire 4810T). This is not fatal but worries users that see this message. Limiting the moule alias to models starting with AOA or DOA for Packard Bell.

| | | | | | | | | | | | | | | | | | | | | | | | | | Added new BIOS versions for following netbooks: Acer 1410, Gateway LT31, Packard Bell DOA150. As the Gateway LT31 machines have different register values for setting and checking the off-state, the "cmd_off" variable has been splitted up to "cmd_off" and "chk_off".
