Subject: [PATCH v2 12/12] fbdev/viafb: Make I2C terminology more inclusive
Date: Fri,  3 May 2024 18:13:33 +0000
Message-Id: <20240503181333.2336999-13-eahariha@linux.microsoft.com>
In-Reply-To: <20240503181333.2336999-1-eahariha@linux.microsoft.com>

I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave"
with more appropriate terms. Inspired by and following on to Wolfram's
series to fix drivers/i2c/[1], fix the terminology for users of
I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists
in the specification.

Compile tested, no functionality changes intended
