eb9671261d Staging: lustre: lustre: mdc: mdc_request: Removed useless variable
Variable rc is initialised and returned by the function without modifying.
Hence replaced rc with it's initial value in the return statement and
removed the variable.

f5717a75db usb: dwc2: make the scheduler handle excessive NAKs better
I'm seeing problems with a d-link dwcl-g122 wifi dongle that
someone sent me. There are reports of other wifi dongles with the
same/similar problem. The devices appear to be NAKing to the point
of confusing the dwc2 driver completely.

The attached patch helps with my d-link dwl-g122 - it's adapted
from the Raspberry Pi dwc_otg driver, which is a modified version
of the Synopsys vendor driver. The error recovery is still valid
after the patch, I think.

acquisition". This results in the interrupt function trying to transfer 0 data
samples.

Validate that the cmd->stop_arg is >= 1 in the (*do_cmdtest) to prevent the
"empty acquisition".

1e2e39effd staging: comedi: pcmuio: return void from pcmuio_start_intr()
This function always returns '0' so the comedi_event() is never done by the
callers.

Change the return type to void and remove the comedi_event() dead code.
