[PATCH 0/3] drm/imagination: Fix pre-existing bugs flagged by Sashiko's review of a VM_BIND series

[Gyeyoung Baek <gye976@gmail.com>]

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

tests/imagination/pvr_vm_map.c, sent separately to igt-dev (see Link
below) and not yet merged, reproduces all three bugs and shows they are
fixed by these patches.
