Subject: ARM/USB: at91/ohci-at91: rename vbus_pin_inverted to vbus_pin_active_low
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8134ff55646bd2c059ddfd0d479882a06d6ef09a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git
ARM/USB: at91/ohci-at91: rename vbus_pin_inverted to vbus_pin_active_low
Allows to configure independently the vbus_pin associated with each port.
Matches usual naming scheme.
