fsi: occ: remove usage of the deprecated ida_simple_xx() API
Patch series "Remove usage of the deprecated ida_simple_xx() API".
The series removes the *last* usages of the deprecated ida_simple_xx() API.
This patch (of 3):
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_range() is inclusive. So, this upper limit, INT_MAX, should
have been changed to INT_MAX-1.
But, it is likely that the INT_MAX 'idx' is valid that the max value passed
to ida_simple_get() should have been 0.
So, allow this INT_MAX 'idx' value now.
