This is a note to let you know that I've just added the patch titled sfp: fix RX_LOS signal handling to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: sfp-fix-rx_los-signal-handling.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From foo@baz Fri Feb 23 11:45:09 CET 2018 From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx> Date: Thu, 30 Nov 2017 13:59:11 +0000 Subject: sfp: fix RX_LOS signal handling From: Russell King <rmk+kernel@xxxxxxxxxxxxxxx> [ Upstream commit acf1c02f023926b8b04672a9e81b1711ae681619 ] The options word is a be16 quantity, so we need to test the flags having converted the endian-ness. Convert the flag bits to be16, which can be optimised by the compiler, rather than converting a variable at runtime.
