Subject: ARM: cns3xxx: use OHCI platform driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6da00dd7b4c2e6678c3eab3573fb94a0c14ec1cf;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: cns3xxx: use OHCI platform driver

This patch converts the cns3xxx platform to use the ohci-platform driver which
is now suitable for use.

A previous patch converted the cns3xxx platform to use the ehci-platform
driver, and thus introduced the need to have power_{on,off} callbacks.
Since both the EHCI and OHCI platform drivers use the same same power_{on,off}
callbacks now, rename them to cns3xx_usb_power_{on,off} to show that they are
shared.
