Subject: net: remove unused 'dev' argument from netif_needs_gso()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8b86a61da37cbbcf4bd6e87fda494a59b1cf16c4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: remove unused 'dev' argument from netif_needs_gso()

In commit 04ffcb255f22 ("net: Add ndo_gso_check") Tom originally
added the 'dev' argument to be able to call ndo_gso_check().

Then later, when generalizing this in commit 5f35227ea34b
("net: Generalize ndo_gso_check to ndo_features_check")
Jesse removed the call to ndo_gso_check() in netif_needs_gso()
by calling the new ndo_features_check() in a different place.
This made the 'dev' argument unused.

Remove the unused argument and go back to the code as before.
