From 0e339447cf2c8b5c742f9be8e2d73bc27b7ac9c4 Mon Sep 17 00:00:00 2001 From: Jeff Johnson Date: Thu, 8 Oct 2015 09:15:53 -0700 Subject: [PATCH] ath10k: cleanup ath10k_mac_register() error handling The logic in the error-handling path of ath10k_mac_register() is divergent from the logic in ath10k_mac_unregister(). Update the ath10k_mac_register() error handling logic to align with the ath10k_mac_unregister() logic.
