[PATCH 3/4] usb: usbtmc: uninitialized symbol 'actual' in usbtmc_ioctl_clear

[Guido Kiener]

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

Fix uninitialized symbol 'actual' in function usbtmc_ioctl_clear.

When symbol 'actual' is not initialized and usb_bulk_msg() fails,
the subsequent kernel debug message shows a random value.

Signed-off-by: Guido Kiener <guido.kie...@rohde-schwarz.com>
Fixes: dfee02ac4bce ("usb: usbtmc: Fix ioctl USBTMC_IOCTL_CLEAR")
