From: Vasanthakumar Thiagarajan Date: Tue, 25 Oct 2011 14:04:21 +0000 (+0530) Subject: ath6kl: Use the other variant of netdev (un)register APIs X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2792972395356254252f12205915a32dce9f50e4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ath6kl: Use the other variant of netdev (un)register APIs Use replace (un)register_netdev() with (un)register_netdevice() so that the same ath6kl function can be used with add_virtual_intf()/del_virtual_intf().
