Subject: [PATCH] usb: host: ohci-pxa27x: Fix and & vs | typo
Date: Fri, 23 Feb 2018 12:33:00 +0000 [thread overview]
Message-ID: <20180223123300.GA1062@mwanda> (raw)
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.
