Commit f8585ce655e9 ("[media] dvb-usb-cxusb: Geniatech T230C support")
sneaked in an unrelated change for the older T230 (not C) model.
As the commit was reverted this change was reverted too,
although likely correct.

The T230C is handled by the dvb-usb-v2/dvbsky.c driver, which should

The module probing logic there is a way more complex than
it should be, and requires some special magic to avoid
stack overflows when KASAN is enabled.
Solve it by creating ancillary functions to setup the
platform data and request module.
Now, the probing functions are cleaner and easier to understand.
As a side effect, the size of the module was reduced by
about 9.7% on x86_64:
Before this patch:
text data bss dec hex filename
51090 14192 96 65378 ff62 drivers/media/usb/em28xx/em28xx-dvb.o
After this patch:
text data bss dec hex filename
44743 14192 96 59031 e697 drivers/media/usb/em28xx/em28xx-dvb.o
Tested with a PCTV 461e device.

With CONFIG_KASAN, the init function uses a large amount of kernel stack:
drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init.part.4':
drivers/media/usb/em28xx/em28xx-dvb.c:2061:1: error: the frame size of 3232 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Using gcc-7 with -fsanitize-address-use-after-scope makes this even worse:
drivers/media/usb/em28xx/em28xx-dvb.c: In function 'em28xx_dvb_init':
drivers/media/usb/em28xx/em28xx-dvb.c:2069:1: error: the frame size of 4280 bytes is larger than 3072 bytes [-Werror=frame-larger-than=]
By splitting out each part of the switch/case statement that has its own local
variables into a separate function, no single one of them uses more than 500 bytes,
and with a noinline_for_stack annotation we can ensure that they are not merged
back together.

Quoting the original report:
It looks like there is a double-free vulnerability in Linux usbtv driver
on an error path of usbtv_probe function. When audio registration fails,
usbtv_video_free function ends up freeing usbtv data structure, which
gets freed the second time under usbtv_video_fail label.
usbtv_audio_fail:
usbtv_video_free(usbtv); =>
v4l2_device_put(&usbtv->v4l2_dev);
=> v4l2_device_put
=> kref_put
=> v4l2_device_release
=> usbtv_release (CALLBACK)
=> kfree(usbtv) (1st time)
usbtv_video_fail:
usb_set_intfdata(intf, NULL);
usb_put_dev(usbtv->udev);
kfree(usbtv); (2nd time)
So, as we have refcounting, use it

This allows the device to define which property flags are set.
Since some cameras offer auto-adjustments for properties (e.g. auto-gain),
the values of other properties (e.g. gain) can change in the camera.

for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.
