Subject: [PATCH 1/2] video: ssd1307fb: Print PWM period using 64-bit format specifier
Date: Mon, 15 Jun 2020 16:16:05 +0200 [thread overview]
Message-ID: <20200615141606.2814208-2-thierry.reding@gmail.com> (raw)
In-Reply-To: <20200615141606.2814208-1-thierry.reding@gmail.com>
The PWM core will soon change the duty cycle and period of PWMs to 64
bits to allow for a broader range of values. Use a 64-bit format
specifier to avoid a warning when that change is made.
