[PATCH 1/2] accep/ivpu: PM: remove broken ivpu_dbg() statements

[PATCH 1/2] accep/ivpu: PM: remove broken ivpu_dbg() statements

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_PM is disabled, the driver fails to build:

It would be possible to rework these statements to only conditionally print
the reference counter, or to make the driver depend on CONFIG_PM, but my
impression is that these are not actually needed at all if the driver generally
works, or they could be put back when required. Just remove all four of these
to make the driver build in all configurations.

[PATCH 2/2] accel/ivpu: avoid duplciate assignment

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

With extra warnings enabled, gcc warns about two assignments
of the same .mmap callback:

In file included from drivers/accel/ivpu/ivpu_drv.c:10:
include/drm/drm_accel.h:31:27: error: initialized field overwritten [-Werror=override-init]
   31 |         .mmap           = drm_gem_mmap

  360 |         DRM_ACCEL_FOPS,
      |         ^~~~~~~~~~~~~~

Remove the unused local assignment.

Yep, two things in flight at the same time.  Thanks for getting to the
