[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit 9fc515bc9e735c10cd327f05c20f5ef69474188d ]

IWL_INFO is not an error but still printed by default.
"can't access the RSA semaphore it is write protected" seems
worrisome but it is not really a problem.
