From: Gabor Juhos Date: Sun, 15 Apr 2012 18:38:05 +0000 (+0200) Subject: ath9k: add an extra boolean parameter to ath9k_hw_apply_txpower X-Git-Tag: accepted/tizen/common/20141203.182822~4724^2~8^2~17 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=64ea57d0c77bd85003b63c6090ddfae114ef6508;p=platform%2Fkernel%2Flinux-arm64.git ath9k: add an extra boolean parameter to ath9k_hw_apply_txpower In order to unifying regulatory limit handling commit ca2c68cc7bc80fc4504fb420df04cce99c9ee6ec (ath9k_hw: clean up tx power handling) introduced a new helper function 'ath9k_hw_apply_txpower', and the direct calls of 'ah->eep_ops->set_txpower' has been replaced by a call of the helper function. This caused a change in the behaviour of the 'ath9k_hw_set_txpowerlimit' function. The purpose of that function is to calculate and store the rate txpower table and the regulatory limit without touching the hardware registers. Before the commit, the 'test' parameter of the function was passed to the 'ah->eep_ops->set_txpower'. Now the calling of the 'set_txpower' function happens indirectly through 'ath9k_hw_apply_txpower', so the 'test' argument of the 'set_txpower' is always 'false'. This patch restores the original behaviour of 'ath9k_hw_set_txpowerlimit' by adding a new argument to 'ath9k_hw_apply_txpower.'
