usb: usbtmc: uninitialized symbol 'actual' in usbtmc_ioctl_abort_bulk_in_tag
Fix uninitialized symbol 'actual' in function usbtmc_ioctl_abort_bulk_in_tag(). When symbol 'actual' is not initialized and usb_bulk_msg() fails, the subsequent kernel debug message shows invalid data. Signed-off-by: Guido Kiener <guido.kiener@rohde-schwarz.com> Fixes: cbe743f1333b ("usb: usbtmc: Fix ioctl USBTMC_IOCTL_ABORT_BULK_IN") Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
