[PATCH] usb: xhci: fix incorrect memset()

From: Arnd Bergmann
Date: Mon Dec 11 2017 - 06:28:24 EST


gcc-8 warnings about the new driver using a memset with a bogus length:

drivers/usb/host/xhci-dbgcap.c: In function 'xhci_dbc_eps_exit':
drivers/usb/host/xhci-dbgcap.c:369:2: error: 'memset' used with length equal to number of elements without multiplication by element size [-Werror=memset-elt-size]

It looks like the author meant to use sizeof() rather than ARRAY_SIZE()
here, so use that.

Fixes: dfba2174dc42 ("usb: xhci: Add DbC support in xHCI driver")
