From 2e2e8d53c3f34684af7a7475098b7524a6b854c2 Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Tue, 23 Sep 2008 15:46:38 -0700 Subject: [PATCH] e1000e: remove failed request for sw/fw/hw flag When the driver fails to acquire the control flag used to serialize NVM and PHY accesses between the driver, firmware and hardware, remove the request for the flag otherwise the hardware might grant the flag when it becomes available but the driver will not release the flag. This could cause the firmware to prevent the driver getting the flag for all future attempts.
