platform: hp_accel: add a i8042 filter to remove HPQ6000 data from kb bus stream

2014-11-07T18:37:03+00:00

Add a i8042 filter to hp_accel to remove accelerometer's data with acpi
id HPQ6000 from keyboard bus stream. The codes sent by accelerometer are
e0 25, e0 26, e0 27 and e0 28. The relevant information is already
passed through /dev/freefall so no need to send these undocumented weird
signals through the keyboard bus. Also, unclogs `dmesg` because atkbd
complained about weird scan codes, saves processing power and disk
space.

hp_accel: Constify ACPI and DMI tables

2014-08-16T08:23:53+00:00

Constify the lis3lv02d_device_ids[] ACPI and the lis3lv02d_dmi_ids[] DMI
tables. There's no need to have them writeable during runtime.

The DriveGuard chips on the new HP laptops are with a new PnP ID
"HPQ6007".  It should be compatible with older chips.

drivers: platform: Mark functions as static in hp_accel.c

2014-01-21T13:44:17+00:00

This patch marks the functions lis3lv02d_acpi_init(),
lis3lv02d_acpi_read() and lis3lv02d_acpi_write() as static in
x86/hp_accel.c because they are not used outside this file.

Thus, it also eliminates the following warnings in x86/hp_accel.c:
drivers/platform/x86/hp_accel.c:91:5: warning: no previous prototype for ‘lis3lv02d_acpi_init’ [-Wmissing-prototypes]
drivers/platform/x86/hp_accel.c:109:5: warning: no previous prototype for ‘lis3lv02d_acpi_read’ [-Wmissing-prototypes]

ACPI: Clean up inclusions of ACPI header files

2013-12-07T00:03:14+00:00

Replace direct inclusions of ,  and
, which are incorrect, with 
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, ,  and 
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
 includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that  be included
prior to  so that the acpi_pci_root declarations the
latter depends on are always there.  And  which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
 as appropriate.

hp_accel: Ignore the error from lis3lv02d_poweron() at resume

2013-05-08T23:59:44+00:00

The error in lis3lv02_poweron() is harmless in the resume path, so
we should ignore it. It is inline with the other usages of lis3lv02_poweron()
and matches the 3.0 code for this routine. This patch is in suse git and
might have missed making it into the mainline.

ACPI: Remove useless type argument of driver .remove() operation

2013-01-25T23:37:24+00:00

The second argument of ACPI driver .remove() operation is only used
by the ACPI processor driver and the value passed to that driver
through it is always available from the given struct acpi_device
object's removal_type field.  For this reason, the second ACPI driver
.remove() argument is in fact useless, so drop it.
