As discussed on: https://github.com/hselasky/webcamd/issues/16 the dib0700 had a regression on Kernel 2.6.39. Such regression didn't affect most devices, in practice, as it seems to happen only under certain circunstances. Michael came up with a solution for the issue (already submitted to the ML) but let's take the opportunity to do a cleanup, as the resulting code was still touching both adapters when an stream off command was issued to one adapter, turning on the other one. After the change, each adapter is idependently controlled by a separate bit, as can be shown when its debug message is turned on (tested on a dual-adapter device: Hauppauge WinTV Nova TD): [608855.124780] adapter 1, streaming ON: 0f 10 12 [608868.189827] adapter 0, streaming ON: 0f 10 13 [608879.584330] adapter 1, streaming OFF: 0f 00 11 [608887.014772] adapter 0, streaming OFF: 0f 00 10 Mauro Carvalho Chehab (2): media: dib0700: cleanup start/stop streaming logic media: dib0700: Only touch one bit when start/stop an adapter Michael Kuron (1): media: dib0700: fix undefined behavior in tuner shutdown drivers/media/usb/dvb-usb/dib0700_core.c | 28 +++++++++++------------- 1 file changed, 13 insertions(+), 15 deletions(-) -- 2.31.1
