comedi: comedi_8254: Replace comedi_8254_init() and comedi_8254_mm_init() `comedi_8254_init()` and `comedi_8254_mm_init()` return `NULL` on failure, but the failure is not necessarily due to lack of memory. Change them to return an `ERR_PTR` value on failure and rename the functions to make it obvious the API has changed. `comedi_8254_init()` has been replaced with `comedi_8254_io_alloc()`, and `comedi_8254_mm_init()` has been replaced with `comedi_8254_mm_alloc()`.

comedi: Move "comedi_8254.h" to <linux/comedi/comedi_8254.h> Some of the header files in "drivers/comedi/drivers/" are common enough to be useful to out-of-tree comedi driver modules. Using them for out-of-tree module builds is hampered by the headers being outside the "include/" directory so it is desirable to move them. There are about a couple of dozen or so Comedi device drivers that use the "comedi_8254" module to add timers based on the venerable 8254 Programmable Interval Timer chip. The macros and declarations to use that module are in the "comedi_8254.h" header file in the comedi "drivers" directory. Move it into "include/linux/comedi/".

comedi: Move the main COMEDI headers Move the main COMEDI driver headers out of "drivers/comedi/" into new directory "include/linux/comedi/". These are "comedidev.h", "comedilib.h", "comedi_pci.h", "comedi_pcmcia.h", and "comedi_usb.h". Additionally, move the user-space API header "comedi.h" into "include/uapi/linux/" and add "WITH Linux-syscall-note" to its SPDX-License-Identifier. Update the "COMEDI DRIVERS" section of the MAINTAINERS file to account for these changes.

staging: comedi: move out of staging directory The comedi code came into the kernel back in 2008, but traces its lifetime to much much earlier. It's been polished and buffed and there's really nothing preventing it from being part of the "real" portion of the kernel. So move it to drivers/comedi/ as it belongs there. Many thanks to the hundreds of developers who did the work to make this happen.
