Currently, a check on spi resides in dynptr_get_spi, while others checking its validity for being within the allocated stack slots happens in is_spi_bounds_valid. Almost always barring a couple of cases (where being beyond allocated stack slots is not an error as stack slots need to be populated), both are used together to make checks. Hence, subsume the is_spi_bounds_valid check in dynptr_get_spi, and return -ERANGE to specially distinguish the case where spi is valid but not within allocated slots in the stack state. The is_spi_bounds_valid function is still kept around as it is a generic helper that will be useful for other objects on stack similar to dynptr in the future.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
