[ Upstream commit 2052138b7da52ad5ccaf74f736d00f39a1c9198c ]
Infinite log printing occurs during fuzz test:
rc rc1: DViCO FusionHDTV DVB-T USB (LGZ201) as ... ... dvb-usb: schedule remote query interval to 100 msecs. dvb-usb: DViCO FusionHDTV DVB-T USB (LGZ201) successfully initialized ... dvb-usb: bulk message failed: -22 (1/0) dvb-usb: bulk message failed: -22 (1/0) dvb-usb: bulk message failed: -22 (1/0) ... dvb-usb: bulk message failed: -22 (1/0)
Looking into the codes, there is a loop in dvb_usb_read_remote_control(), that is in rc_core_dvb_usb_remote_init() create a work that will call dvb_usb_read_remote_control(), and this work will reschedule itself at 'rc_interval' intervals to recursively call dvb_usb_read_remote_control(), see following code snippet:
[...]
This patch, as part of v6.10.3-rc3 breaks my TeVii s480 dual DVB-S2 card, reverting just this patch from v6.10-rc3 fixes the situation again (a co-installed Microsoft Xbox One Digital TV DVB-T2 Tuner keeps working).
Thanks for reporting this ...
So looking at the commit, it must be that one of the usb endpoints is neither a send/receiver bulk endpoint. Would you mind sending a lusb -v of the device, I think something like:
lsusb -v -d 9022:d482
Should do it, or -d 9022::d481
It doesn't show up as 9022:d482 or 9022:d481, but as two 9022:d660.
