But this obviously is fine. However, it's simple enough to work around by just deleting the unlikely() call. We don't do anything with that anyway.

| | | | | | | | | | | | | | | | | | | | | | | | Semaphores don't need to be released from CPU anymore, so clarify the code by deleting nvgpu_semaphore_release() and refactoring __nvgpu_semaphore_release() to nvgpu_semaphore_reset() that only "fast-forwards" the semaphore to a later value. While doing this, the meaning of nvgpu_semaphore_incr() changes, so rename it to nvgpu_semaphore_prepare(). Now it's only used to prepare an nvgpu_semaphore for a value that the HW will increment the sema to. Also change the BUG_ON that guards sema double-inits into just WARN_ON.
