Subject: [PATCH 0/2] platform/mellanox: mlxbf-pmc: Fix module loading

Hi,

The mlxbf-pmc driver fails to load when the firmware reports a new but not
yet implemented performance block. I can reproduce this today with a
Bluefield-3 card and UEFI version 4.6.0-18-g7d063bb-BId13035, since this
reports the new clock_measure performance block.

This[1] patch from Shravan implements the clock_measure support and will
solve the issue. But this series avoids the situation by ignoring and
logging unsupported performance blocks.

NOTE: This series is based on latest linux-next which contains new changes
to mlxbf-pmc.

Luiz Capitulino (2):
  platform/mellanox: mlxbf-pmc: mlxbf_pmc_event_list(): make size ptr
    optional
  platform/mellanox: mlxbf-pmc: Ignore unsupported performance blocks
