Subject: USB: EHCI: ehci-w90x900: remove unuseful functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=fd3ed14ed0790d37c1f82cbaf30838d09da0c39e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

USB: EHCI: ehci-w90x900: remove unuseful functions

The ehci_w90x900_probe function is not doing anything other than
calling usb_w90x900_probe function so ehci_w90x900_probe function
is unuseful that is why removed ehci_w90x900_probe functions and
renamed usb_w90x900_probe function to ehci_w90x900_probe for proper
naming.

The ehci_w90x900_remove function is also not doing anything other
than calling usb_w90x900_remove that is why removed ehci_w90x900_remove
function and renamed usb_w90x900_remove to ehci_w90x900_remove for proper
naming.

This also removes warning of checkpatch.pl script.
