There is a wrong comparison of the total size of the loaded firmware
css->fw->size with the size of a pointer to struct imgu_fw_header.
Turn binary_header into a flexible-array member[1][2], use the
struct_size() helper and fix the wrong size comparison. Notice
that the loaded firmware needs to contain at least one 'struct
imgu_fw_info' item in the binary_header[] array.
with binary_header declared as a flexible-array member is equivalent
to
"css->fw->size < sizeof(struct imgu_fw_header)"
with binary_header declared as a one-element array (as in the original
code).
The replacement of the one-element array with a flexible-array member
also helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

The flush buffer is a special buffer that tells the decoder driver to
send an empty CAPTURE frame to the client with V4L2_BUF_FLAG_LAST set.
We need similar functionality for the encoder ; however currently the
flush buffer depends on decoder-specific structures and thus cannot be
reused with the encoder.
Fix this by testing for this buffer by its VB2 address, and not through
a dedicated flag stored in a higher-level decoder structure. This also
allows us to remove said flag and simplify the code a bit.
Since the flush buffer should never be used in the stateless decoder,
also add safeguards to check against it.

subsequently calling G_FMT on the CAPTURE queue would result in the
unclamped resolution being returned, further inducing the client into

on when it got "too dark", along with other nice features, like
smoothing dead pixels, funky filters, effects and face tracking.
