[ Upstream commit b7cd0da982e3043f2eec7235ac5530cb18d6af1d ]
syzbot reported memory leak in dvb-usb. The problem was
in invalid error handling in dvb_usb_adapter_init().
for (n = 0; n < d->props.num_adapters; n++) {
....
if ((ret = dvb_usb_adapter_stream_init(adap)) ||
(ret = dvb_usb_adapter_dvb_init(adap, adapter_nrs)) ||
(ret = dvb_usb_adapter_frontend_init(adap))) {
return ret;
}
...
d->num_adapters_initialized++;
...
}
In case of error in dvb_usb_adapter_dvb_init() or
dvb_usb_adapter_dvb_init() d->num_adapters_initialized won't be
incremented, but dvb_usb_adapter_exit() relies on it:
for (n = 0; n < d->num_adapters_initialized; n++)
So, allocated objects won't be freed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
