staging: comedi: cb_pcidas: Allow 2-channel commands for AO subdevice

2020-11-05T10:51:57+00:00

commit 647a6002cb41d358d9ac5de101a8a6dc74748a59 upstream. The "cb_pcidas" driver supports asynchronous commands on the analog output (AO) subdevice for those boards that have an AO FIFO. The code (in `cb_pcidas_ao_check_chanlist()` and `cb_pcidas_ao_cmd()`) to validate and set up the command supports output to a single channel or to two channels simultaneously (the boards have two AO channels). However, the code in `cb_pcidas_auto_attach()` that initializes the subdevices neglects to initialize the AO subdevice's `len_chanlist` member, leaving it set to 0, but the Comedi core will "correct" it to 1 if the driver neglected to set it. This limits commands to use a single channel (either channel 0 or 1), but the limit should be two channels. Set the AO subdevice's `len_chanlist` member to be the same value as the `n_chan` member, which will be 2.

staging: comedi: check validity of wMaxPacketSize of usb endpoints found

2020-10-17T06:31:21+00:00

commit e1f13c879a7c21bd207dc6242455e8e3a1e88b40 upstream. While finding usb endpoints in vmk80xx_find_usb_endpoints(), check if wMaxPacketSize = 0 for the endpoints found. Some devices have isochronous endpoints that have wMaxPacketSize = 0 (as required by the USB-2 spec). However, since this doesn't apply here, wMaxPacketSize = 0 can be considered to be invalid.

staging: comedi: addi: Replace HTTP links with HTTPS ones
