SubjectRe: [PATCH] bluetooth: hci_ath: Replace mdelay with msleep in ath_wakeup_ar3k
Hi Jia-Ju,

> ath_wakeup_ar3k() is never called from atomic context.
> It is only called by ath_hci_uart_work() that is only called in
> ath_open() via INIT_WORK().
> All of the above functions do not enter atomic context along the way.
> Despite never getting called from atomic context, ath_wakeup_ar3k() calls
> mdelay() for busy wait.
> That is not necessary and can be replaced with msleep to avoid busy wait.
> This is found by a static analysis tool named DCNS written by myself.
