Subject: proc: remove usage of the deprecated ida_simple_xx() API
Date: Sat, 8 Jun 2024 16:34:20 +0200
ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_max() is inclusive. So a -1 has been added when needed.
