From: Grant Grundler <grundler@chromium.org>

[ Upstream commit 14c76b2e75bca4d96e2b85a0c12aa43e84fe3f74 ]

This doesn't need to be printed every second as an error:
...
<3>[17438.628385] cros-usbpd-charger cros-usbpd-charger.3.auto: Port 1: default case!
<3>[17439.634176] cros-usbpd-charger cros-usbpd-charger.3.auto: Port 1: default case!

[PATCH AUTOSEL 4.19 2/4] i2c: imx-lpi2c: clean rx/tx buffers upon new message

[Sasha Levin]

From: Alexander Stein <alexander.stein@ew.tq-group.com>

[ Upstream commit 987dd36c0141f6ab9f0fbf14d6b2ec3342dedb2f ]

When start sending a new message clear the Rx & Tx buffer pointers in
order to avoid using stale pointers.

[PATCH AUTOSEL 4.19 3/4] efi: sysfb_efi: Add quirk for Lenovo Yoga Book X91F/L

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 5ed213dd64681f84a01ceaa82fb336cf7d59ddcf ]

Another Lenovo convertable which reports a landscape resolution of
1920x1200 with a pitch of (1920 * 4) bytes, while the actual framebuffer
has a resolution of 1200x1920 with a pitch of (1200 * 4) bytes.

[PATCH AUTOSEL 4.19 4/4] verify_pefile: relax wrapper length check

[Sasha Levin]

From: Robbie Harwood <rharwood@redhat.com>

[ Upstream commit 4fc5c74dde69a7eda172514aaeb5a7df3600adb3 ]

The PE Format Specification (section "The Attribute Certificate Table
(Image Only)") states that `dwLength` is to be rounded up to 8-byte
alignment when used for traversal.  Therefore, the field is not required
to be an 8-byte multiple in the first place.

Accordingly, pesign has not performed this alignment since version
0.110.  This causes kexec failure on pesign'd binaries with "PEFILE:
Signature wrapper len wrong".  Update the comment and relax the check.
