The driver may sleep under a spinlock.
The function call path is:
bdisp_device_run (acquire the spinlock)
bdisp_hw_update
bdisp_hw_save_request
devm_kzalloc(GFP_KERNEL) --> may sleep
To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool(DSAC) and checked by my code review.

Since bytesperline always fulfills VDOA width requirements, detile the
whole buffer instead of limiting to visible width. This stops TRY_FMT
from returning -EINVAL for YUYV capture buffers that are not a multiple
of 16 wide.
An alternative would be to always round up width to stride, as we report
the valid image rectange via G_SELECTION (V4L2_SEL_TGT_COMPOSE_DEFAULT),
but that would require all applications to handle the compose default
rectangle properly.

IMHO, there isn't much sense on doing that, and that will just

When iterating through all endpoints using of_graph_get_next_endpoint(),
the refcount of the returned endpoint node is incremented and the refcount
of the node which is passed as previous endpoint is decremented.
So the caller doesn't need to call of_node_put() for each iterated node
except for error exit paths. Otherwise we get "OF: ERROR: Bad
of_node_put() on ..." messages.

timespec is generally deprecated because of the y2038 overflow.
In vivid, the usage is fine, since we are dealing with monotonic
timestamps, but we can also simplify the code by going to ktime_t.
Using ktime_divns() should be roughly as efficient as the old code,
since the constant 64-bit division gets turned into a multiplication
on modern platforms, and we save multiple 32-bit divisions that can be
expensive e.g. on ARMv7.
