Subject: usb: dwc3: gadget: rename phy_power() to phy_suspend()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d7a46a8dfc45191b39daa19c05d3ff74d1881f15;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

usb: dwc3: gadget: rename phy_power() to phy_suspend()

those two functions don't power PHYs, they simply
put them in suspend state. Rename to reflect better
what functions actually do.
