4 | Subject: [PATCH 39/56] mx53loco: Remove unneeded gpio_set_value() | ||
5 | |||
6 | There is no need to set the VBUS power enable to 0 first and then to 1. | ||
7 | |||
8 | Set it to 1 in the gpio_direction_output() function. | ||
9 | |||
10 | While at it, use the standard naming convention for the GPIO comment. | ||
