[PATCH 4/4] usb: usbtmc: uninitialized symbol 'actual' in usbtmc_ioctl_abort_bulk_in_tag

[Guido Kiener]

From: Guido Kiener <guido.kie...@rohde-schwarz.com>

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.kie...@rohde-schwarz.com>
Fixes: cbe743f1333b ("usb: usbtmc: Fix ioctl USBTMC_IOCTL_ABORT_BULK_IN")
