[PATCH v2 09/12] iwlwifi: mvm: assign SAR table revision to the command later

From: Luca Coelho <hidden>
Date: 2021-02-10 12:00:49
Subsystem: intel wireless wifi link (iwlwifi), the rest · Maintainers: Miri Korenblit, Linus Torvalds

From: Luca Coelho <redacted>

The call to iwl_sar_geo_init() was moved to the end of the
iwl_mvm_sar_geo_init() function, after the table revision is assigned
to the FW command.  But the revision is only known after
iwl_sar_geo_init() is called, so we were always assigning zero to it.

Fix that by moving the assignment code after the iwl_sar_geo_init()
function is called.
