[PATCH v2 0/2] drm/imagination: Fix pre-existing bugs flagged by Sashiko's review of a VM_BIND series

[Gyeyoung Baek <gye976@gmail.com>]

These two patches fix pre-existing bugs in this driver that a VM_BIND
series depends on. They address what Sashiko flagged while reviewing
that series (see Link below).

This series is based on drm-misc-fixes, which already includes the
"Fixes for map() path" series (see Link below). Patch 2 is built on top
of 0a8224058a58 from that series.

tests/imagination/pvr_vm_map.c, sent separately to igt-dev (see Link
below) and not yet merged, tests these paths and passes with this
series applied.
