I'm writing again just to be sure that I made my argument clear. When I wrote "[] let's leave the code as it is [currently]" I was referring to the mutex_lock() that is _never_ reached while holding the spinlock that rtw_set_802_11_disassociate() takes before calling _rtw_pwr_wakeup(). Instead, if no one objects, I want to substitute the two "msleep(10);" with "mdelay(10);". However, I'll wait some time just in case someone wants to suggest a better solution.
