I was not familiar with the acquiring/releasing API either, until I met with this bug... Perhaps we can use static checkers to avoid these issues as early as possible. Any suggestions? Best Regards Junjie Mao Martin Pitt [off-list ref] writes:

The driver is not released when ieee80211_register_hw fails in mac80211_hwsim_create_radio, leading to the access to the unregistered (and possibly freed) device in platform_driver_unregister:Many thanks for fixing this! Sorry about that, I don't know these bits very well. Martin
