Andy Shevchenko d4ea1d504d regmap: spi: Fix potential off-by-one when calculating reserved size
If we ever meet a hardware that uses weird register bits and padding,
we may end up in off-by-one error since x/8 + y/8 might not be equal
to (x + y)/8 in some cases.

bits    pad   x/8+y/8 (x+y)/8
4..7    0..3    0       0 // x + y from 4 up to 7
4..7    4..7    0       1 // x + y from 8 up to 11
4..7    8..11   1       1 // x + y from 12 up to 15
8..15   0..7    1       1 // x + y from 8 up to 15
8..15   8..15   2       2 // x + y from 16 up to 23

Fix this by using (x+y)/8.

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 reStructuredText 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.
