Subject: [PATCH 5/6] i2c: efi: avoid 64-bit division
Date: Wed, 14 Aug 2024 11:24:23 +0200 [thread overview]
Message-ID: <20240814092424.39878-5-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20240814092424.39878-1-a.fatoum@pengutronix.de>
I2C message length is 16 bit, so doing a 64-bit division is overkill.
Let's remove the cast and just rely on the usual integer promotion
to 32-bit.
