[PATCH] [v3] Bluetooth: btrsi: rework dependencies

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The linkage between the bluetooth driver and the wireless
driver is not defined properly, leading to build problems
such as:

warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X)
drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':
(.text+0x205): undefined reference to `rsi_bt_ops'

As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.
