Subject: [PATCH] firmware: cs_dsp: Fix endianness conversion in cs_dsp_mock_wmfw.c

In cs_dsp_mock_wmfw_add_coeff_desc() the value stored in longstring->len
needs a cpu_to_le16() conversion.

Fixes: 5cf1b7b47180 ("firmware: cs_dsp: Add mock wmfw file generator for KUnit testing")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202412170233.8DnsdtY6-lkp@intel.com/
