[PATCH v2 0/2] Add missing facility check to ptp_s390 driver

[Sven Schnelle <svens@linux.ibm.com>]

This patchset adds a missing facility check and a check that the 'query
physical clock' (PTFF QPT) function is actually available. If it's not
present, no qpt ptp device will be registered. In order to use ptff_query()
in a module, the first patch adds a EXPORT_SYMBOL() to export
ptff_function_mask.

Changes in v2:
- drop CC check
- add PTFF QAF check
- add patch to export ptff_function_mask

Sven Schnelle (2):
  s390/ptff: Export ptff_function_mask[]
  ptp: ptp_s390: Add missing facility check
