For some unknown reason the LAN9303 switch fail to forward data when switch fabric port 0 TX is disabled during probe. (Write of LAN9303_MAC_TX_CFG_0 in lan9303_disable_processing_port().) In that situation the switch fabric seem to receive frames, because the ALR is learning addresses. But no frames are transmitted on any of the ports. In our system lan9303_probe() is called twice, first time dsa_register_switch() return -EPROBE_DEFER. As an experiment, modified the code to skip writing LAN9303_MAC_TX_CFG_0, port 0 during the first probe. Then the switch works as expected. Resolve the problem by not calling lan9303_disable_processing_port() on port 0 during probe. Ports 1 and 2 are still disabled. Although unsatisfying that the exact failure mechanism is not known, the patch should not cause any harm.

[Linux-stable-mirror] Patch "media: usbtv: fix brightness and contrast controls" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled media: usbtv: fix brightness and contrast controls 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=sum… The filename of the patch is: media-usbtv-fix-brightness-and-contrast-controls.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(a)vger.kernel.org> know about it. >From foo@baz Mon Dec 18 13:28:59 CET 2017 From: Adam Sampson <ats(a)offog.org> Date: Tue, 24 Oct 2017 16:14:46 -0400 Subject: media: usbtv: fix brightness and contrast controls From: Adam Sampson <ats(a)offog.org> [ Upstream commit b3168c87c0492661badc3e908f977d79e7738a41 ] Because the brightness and contrast controls share a register, usbtv_s_ctrl needs to read the existing values for both controls before inserting the new value. However, the code accidentally wrote to the registers (from an uninitialised stack array), rather than reading them. The user-visible effect of this was that adjusting the brightness would also set the contrast to a random value, and vice versa -- so it wasn't possible to correctly adjust the brightness of usbtv's video output. Tested with an "EasyDAY" UTV007 device.
