Subject: ath6kl: Refactor ath6kl_init_hw_start() and ath6kl_init_hw_stop()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ede615d2f043539e23bc4022955dbe0c3ec70ca2;p=linux-beck.git

ath6kl: Refactor ath6kl_init_hw_start() and ath6kl_init_hw_stop()

So that these functions will be used to re-initialize the fw
upon detecting fw error. This refactoring moves ar->state
setting out of core stop/start functionality.
