Geoffrey D. Bennett 7cefc67b2c ALSA: scarlett2: Fix DSP filter control array handling [ Upstream commit `1d24148336` ] scarlett2_add_dsp_ctls() was incorrectly storing the precomp and PEQ filter coefficient control pointers into the precomp_flt_switch_ctls and peq_flt_switch_ctls arrays instead of the intended targets precomp_flt_ctls and peq_flt_ctls. Pass NULL instead, as the filter coefficient control pointers are not used, and remove the unused precomp_flt_ctls and peq_flt_ctls arrays from struct scarlett2_data. Additionally, scarlett2_update_filter_values() was reading dsp_input_count * peq_flt_count values for SCARLETT2_CONFIG_PEQ_FLT_SWITCH, but the peq_flt_switch array is indexed only by dsp_input_count (one switch per DSP input, not per filter). Fix the read count. Fixes: `b64678eb4e` ("ALSA: scarlett2: Add DSP controls") Signed-off-by: Geoffrey D.

README

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.
