Subject: [NET]: dev_put/dev_hold cleanup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=153330618691694af64f39fb56c9de051862380e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[NET]: dev_put/dev_hold cleanup

Get rid of the old __dev_put macro that is just a hold over from pre 2.6
kernel.  And turn dev_hold into an inline instead of a macro.
