suitable for passing to cpmem.

Steve Longerbeam e7268c699b gpu: ipu-v3: Add __ipu_idmac_reset_current_buffer()
Adds __ipu_idmac_reset_current_buffer() that resets a channel's
internal current buffer pointer so that transfers start from buffer
0 on the next channel enable.

This operation is required for channel linking to work correctly,
for instance video capture pipelines that carry out image rotations
will fail after the first streaming unless this function is called
for each channel before re-enabling the channels.

Steve Longerbeam aa52f57894 gpu: ipu-v3: Add ipu_idmac_buffer_is_ready()
Add ipu_idmac_buffer_is_ready(), returns true if the given buffer in
the given channel is set ready (owned by IPU), or false if not ready
(owned by CPU core).

Support has been added for third buffer, there is no support yet for
triple-buffering in idmac channels, but this function checks
buffer-ready for third buffer in case this support is added later.

Azael Avalos f6aac65229 toshiba_acpi: Add extra check to backlight code
Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight
interface to be registered without write support.

This patch changes the set_lcd_brightness function,
checking the returned values for values greater than
zero to avoid registering a broken backlight interface.

Mathias Krause fbe9b79f8c fujitsu-laptop: Mark fujitsu_dmi_table[] DMI table as __initconst
The DMI table is only ever used during initialization. Mark it as
__initconst so its memory can be released afterwards -- roughly 1.5 kB.
In turn, the callback functions can be marked with __init, too.

Mathias Krause 702ef54255 hp-wmi: Add missing __init annotations to initialization code
These functions are only called from other initialization routines, so
can be marked __init, too.

Mathias Krause 8a1a970acd hp_accel: Constify ACPI and DMI tables
Constify the lis3lv02d_device_ids[] ACPI and the lis3lv02d_dmi_ids[] DMI
tables. There's no need to have them writeable during runtime.

Mathias Krause 0f93c5e592 fujitsu-tablet: Mark DMI callbacks as __init code
The DMI table is already marked as __initconst, so can be the callback
functions as they're only used in that context.

Mathias Krause 681480cc56 dell-laptop: Mark dell_quirks[] DMI table as __initconst
The dell_quirks[] DMI table is only ever used during initialization.
Mark it as __initconst so its memory can be released afterwards --
roughly 5.7 kB. In turn, the callback function can be marked with
__init, too.

Also the touchpad_led_init() function can be marked __init as it's only
referenced from dell_init() -- an __init function.

Mathias Krause 76d51dd9a0 acer-wmi: Mark init data and code as such
Quite a lot of code and data of acer-wmi.c is only ever used during
initialization. Mark those accordingly -- and constify, where
appropriate -- so the memory can be released afterwards.

All in all those changes move ~10 kB of code and data to the .init
sections, marking them for release after initialization has finished.
