From 6b598e1eac68b07ebb831258e0667f5ba2834822 Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Wed, 23 Jan 2013 06:50:05 +0000 Subject: e1000e: cleanup: remove e1000e_commit_phy() Remove the function e1000e_commit_phy() and replace the few calls to it with the same function pointer that it would call. The function pointer is almost always set for the devices that access these code paths so there is no risk of a NULL pointer dereference; for the few instances where the function pointer might not be set (i.e. can be called for the few devices which do not have this function pointer set), check for a valid function pointer.
