This skips rate_control_deinitialize() and\nleaks the initialized local->rate_ctrl.\n\nFix this by adding a fail_band label that shares the rate-control cleanup\npath before falling through to the remaining teardown.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nv7.1-rc7.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have a\nsuitable mac80211 device/driver combination to test with, no runtime\ntesting was able to be performed."
