Richard Fitzgerald 5b933c7262 firmware: cs_dsp: Fix overrun of unterminated control name string ... For wmfw format v2 and later the coefficient name strings have a length field and are NOT null-terminated. Use kasprintf() to convert the unterminated string into a null-terminated string in an allocated buffer. The previous code handled this duplication incorrectly using kmemdup() and getting the length from a strlen() of the (unterminated) source string. This resulted in creating a string that continued up to the next byte in the firmware file that just happened to be 0x00.
