Subject: usbnet: smsc95xx: rename FEATURE_AUTOSUSPEND
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eb970ff07c15f13eb474f643fd165ebe3e4e24b2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usbnet: smsc95xx: rename FEATURE_AUTOSUSPEND

The name of FEATURE_AUTOSUSPEND is very misleading and the actual
meaning is remote wakeup, but a device incapable of remote wakeup
still can support USB autosuspend under some situations, so rename
it to avoid misunderstanding.
