Pull chrome platform updates from Benson Leung:
 "CrOS EC:

   - Refactoring of some of cros_ec's headers:

     transport drivers.

   - Response tracing in cros_ec_proto

  Wilco EC:

   - Fix unregistration order.

   - Fix keyboard backlight probing on systems without keyboard
     backlight

<content type='text'>
When aligning the format the pixel format that is being processed shall
be used to figure out alignment constraints, not the currently active
pixel format. The alignment might be part of a try operation and shall
not be effected by the active format. Fix this by looking at the correct
pixel format.

<content type='text'>
Despite using M2M in both the decoder and encoder, this driver used
vb2_v4l2_buffer as its base buffer structure, and placed a list_head
right after the buffer declaration in order to match the layout of a
v4l2_m2m_buffer. This is very dangerous as it means the driver will
break should the layout of v4l2_m2m_buffer change.

Fix this by directly using v4l2_m2m_buffer and updating the sites that
accessed the buffer accordingly.

In vpfe_register_ccdc_device(), failure to allocate dev-&gt;hw_ops
fields calls BUG_ON(). This patch returns the error to callers
instead of crashing. The issue was identified by a static

The driver may sleep while holding a spinlock.
The function call path (from bottom to top) in Linux 4.19 is:

drivers/media/platform/sti/bdisp/bdisp-hw.c, 385:
    msleep in bdisp_hw_reset
drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 341:
    bdisp_hw_reset in bdisp_device_run
drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 317:
    _raw_spin_lock_irqsave in bdisp_device_run

To fix this bug, msleep() is replaced with udelay().

This bug is found by a static analysis tool STCheck written by myself.
