Message-ID: <20150511131952.GD2067@n2100.arm.linux.org.uk>
Date: Mon, 11 May 2015 14:19:52 +0100

Subject: [PATCH] Show proper respect for Heinrich Hertz by using the correct
unit for frequency
The SI unit of frequency is Hertz, named after Heinrich Hertz, and is
given the symbol "Hz" to denote this. "hz" is not the unit of frequency,
and is in fact meaningless.
Fix arch/arm to correctly use "Hz", thereby acknowledging Heinrich Hertz
contribution to the modern world.

There are other instances in drivers/ that really need to be fixed as well.
