From: "Souptick Joarder (HPE)" <jrdr.linux@xxxxxxxxx> Kernel test robot reported below warning -> drivers/net/wireless/ath/wcn36xx/main.c:409:7: warning: Branch condition evaluates to a garbage value [clang-analyzer-core.uninitialized.Branch] Also code walk indicates, if channel is not found in first band, it will break the loop and instead of exit it will go ahead and assign a garbage value in wcn->channel which looks like a bug. Initialize channel with NULL should avoid this issue.
