Most of the non-driver core code should be converted to not use the
lock in the class at all.  They should use a local lock instead.

So how about a patch series that removes the usage of the current
semaphore from the different drivers, and then, a single patch that
converts the semaphore to mutex in the class code, it should not touch
anything outside of the drivers/base/ directory (not including the
driver.h file.)

Sound reasonable?

thanks,
