modpost: disallow *driver to reference .meminit* sections
Drivers must not reference .meminit* sections, which are discarded
when CONFIG_MEMORY_HOTPLUG=n.
The reason for whitelisting "*driver" in the section mismatch check
was to allow drivers to reference symbols annotated as __devinit or
__devexit that existed in the past.
Those annotations were removed by the following commits:
- 54b956b90360 ("Remove __dev* markings from init.h")
- 92e9e6d1f984 ("modpost.c: Stop checking __dev* section mismatches")
Remove the stale whitelist.
