Subject: [PATCH 1/4] mt76: move mt76x02_tx_get_max_txpwr_adj in mt76x02_util.c
Date: Mon,  1 Oct 2018 18:58:17 +0200	[thread overview]
Message-ID: <ce6414cbee0fbb6d407c64e1d4ee32f35cd3c66b.1538411693.git.lorenzo.bianconi@redhat.com> (raw)
In-Reply-To: <cover.1538411693.git.lorenzo.bianconi@redhat.com>

Move mt76x02_tx_get_max_txpwr_adj routine in mt76x02-lib module
since now both mt76x0 and mt76x2 drivers read rate tx power gain from
rate_power data structure. Moreover remove get_max_txpwr_adj function
pointer from mt76_driver_ops data structure
