From 6e6ebf4befa75ebdf28130d0135f3ad3aadc02f8 Mon Sep 17 00:00:00 2001 From: Wey-Yi Guy Date: Fri, 27 Aug 2010 10:41:37 -0700 Subject: [PATCH] iwlwifi: remember the last uCode sysassert error code When sysassert happen, uCode will report the error code, driver dump the information to dmesg. Here also remember the last error code for future reference.
