Subject: [PATCH] usb: host: ohci-pxa27x: Fix and & vs | typo
Date: Sat, 17 Aug 2019 09:55:20 +0300
Message-ID: <20190817065520.GA29951@mwanda> (raw)
In-Reply-To: <20190815123642.GA29583@kroah.com>

The code is supposed to clear the RH_A_NPS and RH_A_PSM bits, but it's
a no-op because of the & vs | typo.  This bug predates git and it was
only discovered using static analysis so it must not affect too many
people in real life.
