[PATCH] drm/amdgpu: fix backport of commit 73dae652dcac

Commit 73dae652dcac ("drm/amdgpu: rework resume handling for display (v2)") missed a small code change when it was backported resulting in an automatic backlight control breakage. Fix the backport.

[PATCH] usb-storage: Add max sectors quirk for Nokia 208

by Lubomir Rintel

This fixes data corruption when accessing the internal SD card in mass storage mode. I am actually not too sure why. I didn't figure a straightforward way to reproduce the issue, but i seem to get garbage when issuing a lot (over 50) of large reads (over 120 sectors) are done in a quick succession. That is, time seems to matter here -- larger reads are fine if they are done with some delay between them. But I'm not great at understanding this sort of things, so I'll assume the issue other, smarter, folks were seeing with similar phones is the same problem and I'll just put my quirk next to theirs. The "Software details" screen on the phone is as follows: V 04.06 07-08-13 RM-849 (c) Nokia TL;DR version of the device descriptor: idVendor 0x0421 Nokia Mobile Phones idProduct 0x06c2 bcdDevice 4.06 iManufacturer 1 Nokia iProduct 2 Nokia 208 The patch assumes older firmwares are broken too (I'm unable to test, but no biggie if they aren't I guess), and I have no idea if newer firmware exists.

[PATCH v3] USB: core: Disable LPM only for non-suspended ports

by Kai-Heng Feng

There's USB error when tegra board is shutting down: [ 180.919315] usb 2-3: Failed to set U1 timeout to 0x0,error code -113 [ 180.919995] usb 2-3: Failed to set U1 timeout to 0xa,error code -113 [ 180.920512] usb 2-3: Failed to set U2 timeout to 0x4,error code -113 [ 186.157172] tegra-xusb 3610000.usb: xHCI host controller not responding, assume dead [ 186.157858] tegra-xusb 3610000.usb: HC died; cleaning up [ 186.317280] tegra-xusb 3610000.usb: Timeout while waiting for evaluate context command The issue is caused by disabling LPM on already suspended ports. For USB2 LPM, the LPM is already disabled during port suspend. For USB3 LPM, port won't transit to U1/U2 when it's already suspended in U3, hence disabling LPM is only needed for ports that are not suspended.
