comedi: comedi_8254: Replace comedi_8254_init() and comedi_8254_mm_init()

2023-10-05T11:34:04Z

`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()`.

drivers: comedi: replace ternary operator with min()

2022-05-19T16:54:45Z

Fix the following coccicheck warning: drivers/comedi/drivers.c:857:12-13: WARNING opportunity for min(). min() macro is defined in include/linux/minmax.h. It avoids multiple evaluations of the arguments when non-constant and performs strict type-checking.

comedi: Move the main COMEDI headers

2021-11-26T15:48:59Z

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

2021-04-15T07:26:25Z

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.
