2012-06-26ideapad: uninitialized data in ideapad_acpi_add()Dan Carpenter
We only initialize the high bits of "cfg". It probably doesn't cause a problem given that this is platform specific code and doesn't have to worry about endianness etc. But it's sort of messy. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>
2012-05-31ideapad: generate valid key event onlyIke Panhc
Otherwise will generate KEY_UNKNOWN on un-listed vpc event, which means nothing and is hard for user to report the detail of the event. Signed-off-by: Ike Panhc <ike.pan@canonical.com> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2011-10-24ideapad: add event for Novo keyIke Panhc
Novo key is the Lenovo define key on every ideapads, which has two definition. Long press and short click. Driver will report KEY_PROG1 on short click and KEY_PROG2 when long press. On pre-install OS for ideapads there are application waiting for the event and there is no such application for Linux yet, so I think to report KEY_PROG is fine in anyway. Also change the scancode from hex to decimal because they are related to vpc bit in notify function which is in decimal.

ideapad_acpi_add error path In the case of ideapad_backlight_init() failure, we need to free the resources allocated by ideapad_input_init(). Aslo drop __devexit annotation for ideapad_input_exit() because we also call it in ideapad_acpi_add() error path.

BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=25922 On ideapad Y530, the brightness key notify will be blocked if the last notify is not responsed by getting the brightness value. Read value when we get the notify shall fix the problem and will not have any difference on other ideapads.

2010-10-21ideapad: Add param: no_bt_rfkillIke Panhc
Add new module parameter that force module not to register bluetooth rfkill. There is report that saying using this bluetooth rfkill to enable/disable bluetooth will let bluetooth device initial failed when enable on Lenovo ideapad S12. Fortunately there is another rfkill registered by bluetooth driver for S12 and user can shutdown the bluetooth by either bluetooth driver or HW RF switch. For dual OS user, it may have some trouble that using Linux after turning off bluetooth with another OS if we do not register bluetooth rfkill at all. So we will force bluetooth enable when no_bt_rfkill=1.

2010-10-21ideapad: Change the driver name to ideapad-laptopIke Panhc
