Subject: [PATCH] xhci: Drop superfluous initialization in xhci_queue_ctrl_tx()
Date: Wed,  6 Feb 2019 16:03:31 -0800	[thread overview]
Message-ID: <20190207000331.7547-1-andrew.smirnov@gmail.com> (raw)

Simplify filed's initialization by directly assigning its final value
instead of initializing the variable to sero and then bitwise or-ing
it.
