Subject: [PATCH 1/4] i2c: designware: Create shared header hosting driver name
Date: Tue, 23 Apr 2024 16:36:19 -0700 [thread overview]
Message-ID: <20240423233622.1494708-2-florian.fainelli@broadcom.com> (raw)
In-Reply-To: <20240423233622.1494708-1-florian.fainelli@broadcom.com>
We have a number of drivers that reference the string "i2c_designware"
yet this is copied all over the places with opportunities for this
string being mis-used. Create a shared header that defines this as a
constant that other drivers can reference.
