Sphinx 3.x broke support for the cdomain.py extension, as the c domain code was rewritten. Due to that, the c tags need to be re-written, in order to use the new c domain notation. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Description
|
|
===========
|
|
|
|
If the bus has been automatically powered off due to power overload,
|
|
this ioctl call restores the power to the bus. The call requires
|
|
read/write access to the device. This call has no effect if the device
|
|
is manually powered off. Not all Digital TV adapters support this ioctl.
|
|
|
|
Return Value
|
|
============
|
|
|
|
On success 0 is returned.
|
|
|
|
On error -1 is returned, and the ``errno`` variable is set
|
|
appropriately.
|
|
|
|
Generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
