Subject: [PATCH] ath9k: refactor ar9003_hw_spur_mitigate_ofdm
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8

Git-commit: 193025378c446d53fa36bfefc33c170f1ec374c8
Patch-mainline: v5.19-rc1
References: bsc#1206451

Similar to ar9003_hw_spur_mitigate_mrc_cck, simplify the code by using
ar9003_get_spur_chan_ptr. This may also be required for QCN550x support,
to provide an abstraction over the underlying EEPROM format.
