This is a note to let you know that I've just added the patch titled bus: ti-sysc: Fix uninitialized framedonetv_irq to the 5.7-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: bus-ti-sysc-fix-uninitialized-framedonetv_irq.patch and it can be found in the queue-5.7 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 34ac0285d862e10911641b6b86aaedf4b893a6b6 Author: Tony Lindgren <tony@xxxxxxxxxxx> Date: Sun May 31 12:37:54 2020 -0700 bus: ti-sysc: Fix uninitialized framedonetv_irq [ Upstream commit 085bc0e576a4bf53b67a917c54908f299a2fb949 ] We are currently only setting the framedonetv_irq disabled for the SoCs that don't have it. But we are never setting it enabled for the SoCs that have it. Let's initialized it to true by default.
