From 246d2bfcf244326c43dcfffcecfdf684b8a4513d Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 17 May 2020 16:26:00 +0200 Subject: [PATCH] net: pcnet: Move private data allocation to initialize The private data allocation does not have to be done every time the NIC is initialized at run time, move the allocation to initialize function, which means it will be done only once when the driver starts.
