Factor the shared logic into common helpers. Patch 1 is a preparatory, no-functional-change rename of struct m3_mem_region to struct ath12k_fw_mem_region, since the type is also used for the aux_uc region and the old name no longer reflects its purpose. Patch 2 refactors the shared free/load logic into ath12k_qmi_free_mem_region() and ath12k_qmi_fw_mem_load(), and rewires the m3 and aux_uc wrappers to use them. --- Changes in v2: - Addressed the review comments. --- Madhavan Ganesan (2): wifi: ath12k: rename m3_mem_region to ath12k_fw_mem_region wifi: ath12k: refactor m3 and aux_uc firmware memory handling drivers/net/wireless/ath/ath12k/qmi.c | 168 ++++++++++++---------------------- drivers/net/wireless/ath/ath12k/qmi.h | 6 +- 2 files changed, 60 insertions(+), 114 deletions(-) --- base-commit: a2da7677eb9a12e7860814b70a1f6f5b0e347d7d change-id: 20261103-m3_and_aux_ucode-8337b881155c
