[PATCH 2/4] usb: usbtmc: uninitialized symbol 'actual' in usbtmc_read

[Guido Kiener]

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

Fix uninitialized symbol 'actual' in function usbtmc_read.

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: d7604ff0dc01 ("usb: usbtmc: Optimize usbtmc_read")
