Pull SoC driver updates from Arnd Bergmann:
 "These are the updates for SoC specific drivers and related subsystems:

   - Firmware driver updates for SCMI, FF-A and SMCCC firmware
     interfaces, adding support for additional firmware features
     including SoC identification and FF-A SRI callbacks as well as
     various bugfixes

   - Memory controller updates for Nvidia and Mediatek

   - Reset controller support for microchip sam9x7 and imx8qxp/imx8qm

   - New hardware support for multiple Mediatek, Renesas and Samsung
     Exynos chips

   - Minor updates on Zynq, Qualcomm, Amlogic, TI, Samsung, Nvidia and
     Apple chips

  There will be a follow up with a few more driver updates that are
  still causing build regressions at the moment"

Qualcomm driver fixes for v6.14

Fixes a locking issue in the PDR implementation, which manifest itself
as transaction timeouts during the startup procedure for some
remoteprocs.

A registration race is fixed in the custom efivars implementation,
resolving reported NULL pointer dereferences.

Error handling related to tzmem allocation is corrected, to ensure that
the allocation error is propagated.

Lastly a trivial merge mistake in pmic_glink is addressed.

When some client process A call pdr_add_lookup() to add the look up for
the service and does schedule locator work, later a process B got a new
server packet indicating locator is up and call pdr_locator_new_server()
which eventually sets pdr-&gt;locator_init_complete to true which process A
sees and takes list lock and queries domain list but it will timeout due
to deadlock as the response will queued to the same qmi-&gt;wq and it is
ordered workqueue and process B is not able to complete new server
request work due to deadlock on list lock.

Fix it by removing the unnecessary list iteration as the list iteration
is already being done inside locator work, so avoid it here and just
call schedule_work() here.

               req-&gt;service_name,
               ret);

Timeout error log due to deadlock:

"
 PDR: tms/servreg get domain list txn wait failed: -110
 PDR: service lookup for msm/adsp/sensor_pd:tms/servreg failed: -110
"

Thanks to Bjorn and Johan for letting me know that this commit also fixes
an audio regression when using the in-kernel pd-mapper as that makes it
easier to hit this race. [1]

When some client process A call pdr_add_lookup() to add the look up for
the service and does schedule locator work, later a process B got a new
server packet indicating locator is up and call pdr_locator_new_server()
which eventually sets pdr-&gt;locator_init_complete to true which process A
sees and takes list lock and queries domain list but it will timeout due
to deadlock as the response will queued to the same qmi-&gt;wq and it is
ordered workqueue and process B is not able to complete new server
request work due to deadlock on list lock.

Fix it by removing the unnecessary list iteration as the list iteration
is already being done inside locator work, so avoid it here and just
call schedule_work() here.

<title>genirq: Remove leading space from irq_chip::irq_print_chip() callbacks</title>

The space separator was factored out from the multiple chip name prints,
but several irq_chip::irq_print_chip() callbacks still print a leading
space.  Remove the superfluous double spaces.
