Takashi Iwai ad4f93ca41 ALSA: memalloc: Use proper SG helpers for noncontig allocations
The recently introduced non-contiguous page allocation support helpers
are using the simplified code to calculate the page and DMA address
based on the vmalloc helpers, but this isn't quite right as the vmap
is valid only for the direct DMA.

This patch corrects those accessors to use the proper SG helpers
instead.

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.
