Both ab8500_regulator_mode_ops and ab8500_regulator_ops do not have volt_table
setting, thus we can not use regulator_list_voltage_table for them.
However, they have min_uV setting with n_voltages = 1, so use
regulator_list_voltage_linear instead.
Also remove setting set_voltage_time_sel for ab8500_regulator_mode_ops.
It is used only for fixed voltage, so it does not need to implement

At http://marc.info/?l=linux-acpi&m=135769405622667&w=2 thread,
Toshi Kani mentioned as follows:
"I have a question about the change you made in commit 65479472 in
acpi_memhotplug.c. This change seems to require that
acpi_memory_enable_device() calls add_memory() to add all memory ranges
represented by memory device objects at boot-time, and keep the results
be used for hot-remove.
If I understand it right, this add_memory() call fails with EEXIST at
boot-time since all memory ranges should have been added from EFI memory
table (or e820) already. This results all memory ranges be marked as !
enabled & !failed. I think this means that we cannot hot-delete any
memory ranges presented at boot-time since acpi_memory_remove_memory()
only calls remove_memory() when the enabled flag is set. Is that
correct?"
Above mention is correct. Thus even if memory device supports hotplug,
memory presented at boot-time cannot be hot removed since the memory
device's acpi_memory_info->enabled is always 0.
This patch changes to set 1 to "acpi_memory_info->enabled" of memory
device presented at boot-time for hot removing the memory device.

In particular, this fixes brightness control initialization for all
devices that return index values from _BQC and don't happen to have the
initial index set by the BIOS in their _BCL table. One example for that
is the Dell Inspiron 15R SE (model number 7520).
What happened for those devices is that acpi_init_brightness queried the
initial brightness by calling acpi_video_device_lcd_get_level_current.
This called _BQC, which returned e.g. 13. As _BQC_use_index isn't
determined at this point (and thus has its initial value of 0), the
index isn't converted into the actual level. As '13' isn't present in
the _BCL list, *level is later overwritten with brightness->curr, which
was initialized to max_level (100) before. Later in
acpi_init_brightness, level_old (with the value 100) is used as an index
into the _BCL table, which causes a value outside of the actual table to
be used as input into acpi_video_device_lcd_set_level(). Depending on
the (undefined) value of that location, this call will fail, causing the
brightness control for the device in question not to be enabled.
Fix that by returning the raw value returned by the _BQC call in the
initialization case.

When the kernel calls _OSC with OSC_SB_HOTPLUG_OST_SUPPORT bit
set at boot-time, the OS is responsible for calling _OST for
ACPI hotplug events. However, when hotplug.enabled attribute
is unset for ACPI scan drivers, their notify handlers are removed
and _OST is not called for ACPI hotplug events as a result.
This patch keeps the notify handler of ACPI scan drivers,
acpi_hotplug_notify_cb(), installed regardless of the state of
hotplug.enabled. The notify handler then checks if hotplug.enabled
is set for the associated scan handler. If unset, the notify
handler calls _OST with a proper error code. The patch also
eliminates ACPI namespace walk when hotplug.enabled is changed
via sysfs.
