Ravulapati Vishnu Vardhan Rao b0cd740a31 ASoC: codecs: tx-macro: Fix for KASAN: slab-out-of-bounds 
[ Upstream commit e5e7e398f6 ]

When we run syzkaller we get below Out of Bound.
    "KASAN: slab-out-of-bounds Read in regcache_flat_read"

    Below is the backtrace of the issue:

    dump_backtrace+0x0/0x4c8
    show_stack+0x34/0x44
    dump_stack_lvl+0xd8/0x118
    print_address_description+0x30/0x2d8
    kasan_report+0x158/0x198

    regcache_flat_read+0x10c/0x110
    regcache_read+0xf4/0x180
    _regmap_read+0xc4/0x278
    _regmap_update_bits+0x130/0x290
    regmap_update_bits_base+0xc0/0x15c
    snd_soc_component_update_bits+0xa8/0x22c
    snd_soc_component_write_field+0x68/0xd4
    tx_macro_digital_mute+0xec/0x140

    Actually There is no need to have decimator with 32 bits.
    By limiting the variable with short type u8 issue is resolved.

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 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.
