[greybus-dev] Re: [PATCH] staging: greybus: uart: replace DEFINE_IDR with DEFINE_XARRAY_ALLOC

DEFINE_IDR is deprecated in favour of DEFINE_XARRAY_ALLOC. Replace the tty_minors IDR with an XArray and update all call sites:

idr_alloc() -> xa_alloc() idr_find() -> xa_load() idr_remove() -> xa_erase() idr_destroy() -> xa_destroy()

Also remove the now-unused <linux/idr.h> include and add <linux/xarray.h>.

I am pretty sure I have rejected this same patch multiple times in the past. Please see the mailing list archives for why.
