linux/include/trace/events/regmap.h
Linus Torvalds 250f6715a4 The following text was taken from the original review request:
"[RFC PATCH 0/2] audit of linux/device.h users in include/*"
 		https://lkml.org/lkml/2012/3/4/159
 --
 
 Nearly every subsystem has some kind of header with a proto like:
 
 	void foo(struct device *dev);
 
 and yet there is no reason for most of these guys to care about the
 sub fields within the device struct.  This allows us to significantly
 reduce the scope of headers including headers.  For this instance, a
 reduction of about 40% is achieved by replacing the include with the
 simple fact that the device is some kind of a struct.
 
 Unlike the much larger module.h cleanup, this one is simply two
 commits.  One to fix the implicit <linux/device.h> users, and then
 one to delete the device.h includes from the linux/include/ dir
 wherever possible.
