[PATCH 0/2] media: streamzap: fix issues with the implementation of usb driver callbacks

[Murad Masimov]

These patches fix two URB-handling related problems in streamzap driver.
The first one fixes a race condition that leads to a kernel panic as
reported by Syzkaller [1]. The second patch prevents bugs by ensuring
that data received by the driver is processed only if URB status is 0.
It also complies with how other similar usb drivers are written.
