Subject: [PATCH V3] media: ov5640: Fix check for PLL1 exceeding max allowed rate
Date: Wed,  4 Dec 2019 07:35:42 -0600
Message-ID: <20191204133542.17239-1-aford173@gmail.com> (raw)

The PLL calculation routine checks the wrong variable name 'rate'
when it should be called '_rate' when checking to see whether or
not the PLL1 output frequency exceeds 1GHz.

This patch changes it to the correct variable '_rate'

Fixes: aa2882481cad ("media: ov5640: Adjust the clock based on the expected rate")

V3:  Add Fixes Tag.
V2:  No code change.  Only change commit description to be less confusing.
