The bf5xx-i2s{,-pcm} and bf5xx-tdm{-pcm} drivers are nearly identical. Both are
for the same hardware each supporting a slight different subset of the hardware.
The bf5xx-i2s driver supports 2 channel I2S mode while the bf5xx-tdm driver
supports TDM mode and channel remapping. This patch adds support for TDM mode
and channel remapping to the bf5xx-i2s driver so that we'll eventually be able
to retire the bf5xx-tdm driver. Unfortunately the hardware is fixed to using 8
channels in TDM mode. The bf5xx-tdm driver jumps through a few hoops to make it
work well with other channel counts as well:
* Don't support mmap
* Translate between internal frame size (which is always 8 * sample_size)
and ALSA frame size (which depends on the channel count)
* Have special copy and silence callbacks which are aware of the mismatch
between internal and ALSA frame size
* Reduce the maximum buffer size to ensure that there is enough headroom for
dummy data.
The bf5xx-i2s driver is going to use the same mechanisms when being used int
TDM mode.

Switch back to pre commit 1c7b13fe65 list splicing logic for active I/O
shutdown with tcm_qla2xxx + ib_srpt fabrics.
The original commit was done under the incorrect assumption that it's safe to
walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after
sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting()
during session shutdown.
So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list
during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to
allow wait_for_completion() + TFO->release_cmd() to occur without having to
walk ->sess_cmd_list after the list_splice.
Also add a check to exit if target_sess_cmd_list_set_waiting() has already
been called, and add a WARN_ON to check for any fabric bug where new se_cmds
are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already
been set.

menu_add_prop() applies upper menus' visibilities to actual prompts
by AND-ing the prompts visibilities with the upper menus ones.
This creates a further reference to the menu's visibilities and when
the expression reduction functions do their work, they may remove or
modify expressions that have multiple references, thus causing
unpredictable side-effects.
The following example Kconfig constructs a case where this causes
problems: a menu and a prompt which's visibilities depend on the same
symbol. When invoking mconf with this Kconfig and pressing "Z" we
see a problem caused by a free'd expression still referenced by the
menu's visibility:
------------------------------------------------------------------------
mainmenu "Kconfig Testing Configuration"
config VISIBLE
def_bool n
config Placeholder
bool "Place holder"
menu "Invisible"
visible if VISIBLE
config TEST_VAR
bool "Test option" if VISIBLE
endmenu
------------------------------------------------------------------------
This patch fixes this problem by creating copies of the menu's
visibility expressions before AND-ing them with the prompt's one.

The divisor adjustment code to ensure that a divisor is not rounded down,
thereby giving a rate higher than requested, is unnecessary and in some
instances results in the actual rate being much lower than requested due to
rounding errors.
The test is already performed in vtwm_dclk_round_rate(), which is always
called when clk_set_rate is called. Due to rounding errors in the line:
divisor = parent_rate / rate (clk-vt8500.c:160) we will sometimes end up
adjusting the divisor twice - first in round_rate and then again in set_rate.
This patch removes the test/adjustment in vtwm_dclk_set_rate.

The WM8850 has a different PLL clock to the previous versions. This
