after copying data to stream buffer.
After that, there is no need to make a workaround for poll function.

Fix build errors when RADIO_TEA575X=y, VIDEO_BT848=m, and VIDEO_DEV=m.
The build errors occur due to [in drivers/media/Makefile]:
obj-$(CONFIG_VIDEO_DEV) += radio/
so the (would be) builtin tea575x.o is not being built.
This is also due to drivers/media/radio/Kconfig declaring a bool
Kconfig symbol (RADIO_ADAPTERS) that depends on a tristate (VIDEO_DEV),
so when VIDEO_DEV=m, RADIO_ADAPTERS becomes =y, and then the drivers
that depend on RADIO_ADPATERS can be configured as builtin (=y) or
as loadable modules (=m).
Fix this by converting RADIO_ADAPTERS to a tristate symbol instead
of a bool symbol.
Fixes these build errors:

Syzbot reported that -1 is used as array index. The problem was in
missing validation check.
hdw->unit_number is initialized with -1 and then if init table walk fails
this value remains unchanged. Since code blindly uses this member for
array indexing adding sanity check is the easiest fix for that.
hdw->workpoll initialization moved upper to prevent warning in
__flush_work.

High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2.
They describe the same video encoding method.
So for handling their behavior is the same.
However, when external camera device describes this encoding method,
some use hevc, some use h265.
There is no uniform specification to describe this encoding method.
So if an external camera device use h265 to describe this encoding method,
driver will not recognize it.
Therefore, this patch is to enable driver to read HEVC/H265

The list iterator will point to a bogus position containing HEAD if
the list is empty or the element is not found in list. This case
should be checked before any use of the iterator, otherwise it will
lead to a invalid memory access. The missing check here is before
"pin = iterm->id;", just add check here to fix the security bug.
In addition, the list iterator value will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the element is not found in list, considering
the (mis)use here: "if (iterm == NULL".
Use a new value 'it' as the list iterator, while use the old value
'iterm' as a dedicated pointer to point to the found element, which
1. can fix this bug, due to 'iterm' is NULL only if it's not found.
2. do not need to change all the uses of 'iterm' after the loop.
3. can also limit the scope of the list iterator 'it' *only inside*
the traversal loop by simply declaring 'it' inside the loop in the
future, as usage of the iterator outside of the list_for_each_entry
is considered harmful. https://lkml.org/lkml/2022/2/17/1032
