2016-09-15gpio: don't include module.h in shared driver headerPaul Gortmaker1-1/+1
Most shared headers in include/linux don't need to know what the internals of a struct module are; all they care about is that it is a struct and hence they may require a pointer to one. The advantage in this is that module.h is including a lot of stuff itself, and an otherwise empty C file that just contains module.h will result in ~750kB from CPP (compared to say 12kB from init.h) So we have approximately 50 instances of "struct module;" in the various include/linux headers already that help us keep module.h out of other headers; here we do the same for gpio.
