Analyze and fix the following issue in the Linux kernel code: wifi: ath12k: fix ar->supports_6ghz usage during hw register
Problem Details: In the ath12k_mac_hw_register() function's context, ar is an iterator variable, and there is no assurance that the last ar will be the one with 6 GHz enabled. Therefore, checking directly ar->supports_6ghz outside the loop is not appropriate. Additionally, 6 GHz lacks HT capabilities. To obtain the su...
