change_queue_depth allows changing per-target queue depth via sysfs. It also allows the SCSI midlayer to ramp down the number of concurrent inflight requests in response to a SCSI BUSY status response and allows the midlayer to ramp the count back up to the device maximum when the BUSY condition has resolved.

It's not a core function, and the matching atomic functions are also not in the core. Plus the suspend/resume helper is also already there. Needs a tiny bit of open-coding, but less midlayer beats that I think.

It's not a core function, and the matching atomic functions are also not in the core. Plus the suspend/resume helper is also already there. Needs a tiny bit of open-coding, but less midlayer beats that I think. v2: Rebase onto ast (which gained a new user).

Amdgpu and nouveau call vga_switcheroo_process_delayed_switch() from their lastclose callbacks. Call it from drm_lastclose(), so that the driver functions can finally be removed. Only PCI devices with enabled switcheroo do the delayed switching. The call has no effect on other hardware. v2: - move change to drm_lastclose() (Sima) - update docs for vga_switcheroo_process_delayed_switch()
