Add driver for Maxim Integrated MAX7360 GPIO/GPO controller.
Two sets of GPIOs are provided by the device:
- Up to 8 GPIOs, shared with the PWM and rotary encoder functionalities.
These GPIOs also provide interrupts on input changes.
- Up to 6 GPOs, on unused keypad columns pins.

The audio codec is found in Qualcomm PM2250/PM4125 PMICs and is used on
platforms like Qualcomm QCM2290. It has soundwire interface and
corresponding RX and TX slave devices.
It has only two input channels: HPH left and right. The line output (LO)
is linked to HPHL so the hardware has some limitations regarding concurrent
playback via HPH and LO for instance.
The codec driver also uses WCD MBCH framework. The MBHC functionality is
implemented in a minimalistic way to enable IRQs and avoid different
issues with IRQs.

drm_for_each_bridge_in_chain() iterates ofer the bridges in an encoder
chain without protecting the lifetime of the bridges using
drm_bridge_get/put(). This creates a risk window where the bridge could be
freed while iterating on it. Users of drm_for_each_bridge_in_chain() cannot
solve this reliably.
Add variant of drm_for_each_bridge_in_chain() that gets/puts the bridge
reference at the beginning/end of each iteration, and puts it if breaking
ot of the loop.
Note that this requires adding a new drm_bridge_get_next_bridge_and_put()
function because, unlike similar functions as __of_get_next_child(),
drm_bridge_get_next_bridge() gets the "next" pointer but does not put the
"prev" pointer. Unfortunately drm_bridge_get_next_bridge() cannot be
modified to put the "prev" pointer because some of its users rely on
this, such as drm_atomic_bridge_propagate_bus_flags().
Also deprecate drm_for_each_bridge_in_chain(), in preparation for removing
it after converting all users to the scoped version.

pointer
Currently drm_bridge_connector_init() reuses the 'bridge' variable, first
as a loop variable in the long drm_for_each_bridge_in_chain() and then in
the HDMI-specific code as a shortcut to bridge_connector->bridge_cec.
We are about to remove the 'bridge' loop variable for
drm_for_each_bridge_in_chain() by moving to a scoped version of the same
macro, which implies removing the 'bridge' variable from the main function
scope. Additionally reusing the variable can make such long function less
readable.
Similarly to what commit 6f727c838ea8 ("drm/bridge-connector: Fix bridge in
drm_connector_hdmi_audio_init()") already did for the audio HDMI bridge,
use n local variable inside the scopes where it is needed as a
bridge_connector->bridge_hdmi_cec shortcut to make its scope clearer as
well as to allow removing the 'bridge' variable in an upcoming commit.

alloc_slab_obj_exts() should mark failed obj_exts vector allocations
independent on whether the vector is being allocated for a new or an

slabs. Fix this by marking failed allocations unconditionally.

When object extension vector allocation fails, we set slab->obj_exts to
OBJEXTS_ALLOC_FAIL to indicate the failure. Later, once the vector is
successfully allocated, we will use this flag to mark codetag references
stored in that vector as empty to avoid codetag warnings.
slab_obj_exts() used to retrieve the slab->obj_exts vector pointer checks
slab->obj_exts for being either NULL or a pointer with MEMCG_DATA_OBJEXTS
bit set. However it does not handle the case when slab->obj_exts equals
OBJEXTS_ALLOC_FAIL. Add the missing condition to avoid extra warning.

Merge series from Mohammad Rafi Shaik <mohammad.rafi.shaik@oss.qualcomm.com>:
Fix the lpaif_type configuration for the I2S interface.
The proper lpaif interface type required to allow DSP to vote
appropriate clock setting for I2S interface and also Add support
for configuring the DAI format on MI2S interfaces to allow setting
the appropriate bit clock and frame clock polarity, ensuring correct
audio data transmissionover MI2S.

On Intel CPUs, the default retbleed mitigation is IBRS/eIBRS but this
requires that a similar spectre_v2 mitigation is applied. If the user
selects a different spectre_v2 mitigation (like spectre_v2=retpoline) a
warning is printed but sysfs will still report 'Mitigation: IBRS' or
'Mitigation: Enhanced IBRS'. This is incorrect because retbleed is not
mitigated, and IBRS is not actually set.
Fix this by choosing RETBLEED_MITIGATION_NONE in this scenario so the
kernel correctly reports the system as vulnerable to retbleed.
