Subject: [PATCH 3/5] i2c: aspeed: Mask IRQ status to relevant bits
Date: Thu, 20 Aug 2020 11:11:50 -0500 [thread overview]
Message-ID: <20200820161152.22751-4-eajames@linux.ibm.com> (raw)
In-Reply-To: <20200820161152.22751-1-eajames@linux.ibm.com>
Mask the IRQ status to only the bits that the driver checks. This
prevents excessive driver warnings when operating in slave mode
when additional bits are set that the driver doesn't handle.
