[PATCH 1/3] mt76x2: dfs: avoid tasklet scheduling during mt76x2_dfs_init_params()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Substitute tasklet_kill with tasklet_disable/tasklet_enable in order to
guarantee dfs tasklet can not be executed during dfs parameter
initialization
