Lv Zheng 8b48463f89 ACPI: Clean up inclusions of ACPI header files
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
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,
<linux/acpi.h> 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 <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> 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
<linux/acpi.h> as appropriate.

Hanjun Guo 11f9c3218b Staging / quickstart: remove reduplicate if(acpi_disabled) check
In acpi_bus_register_driver(), there is an if (acpi_disabled) check,
so the if(acpi_disabled) before it is reduplicate, remove it.

Greg Kroah-Hartman 3b7cf04f87 staging: quickstart: fix up sysfs file permissions
Use the default DEVICE_ATTR_RO/RW macros to specify the file permissions
better, and make them easier to audit.

And did we really want any user to be able to write to this file, I kind
of doubt it...

Rafael J. Wysocki 51fac8388a ACPI: Remove useless type argument of driver .remove() operation
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.

zero on success and negative error codes on failure, but acpi_status is
