v2: Return false instead of continuing - reject the command instead of
ignoring.

MI_STORE_REGISTER_MEM. When trying to check
such command, the find_reg would dereference NULL pointer.
Now it will just return NULL meaning that the register was not found and the
command will be rejected.

the offset ends up outside of the
command length, just ignore it.

it is worth
sharing it here.
Michal Srb (2):
drm/i915/cmdparser: Check reg_table_count before derefencing.
drm/i915/cmdparser: Do not check bits past the cmd length.

The io_mem_pfn field was added in commit
ea642c3216cb2a60d1c0e760ae47ee85c9c16447
