-This reverts commit f3de5d857bb2362b00e2a8d4bc886cd49dcb66db.

|
|
|
-That commit broke USB on all routers that have USB always powered on and
|
|
|
-don't require toggling any GPIO. It's a majority of devices actually.
|
|
|
-
|
|
|
-The original code worked and seemed safe: vcc GPIO is optional and
|
|
|
-bcma_hci_platform_power_gpio() takes care of checking the pointer before
|
|
|
-using it.
|
|

|
|
-This revert fixes:
