    Subject[PATCH for stable] cx25821: Remove bad strcpy to read-only char*
    Hi Greg,

    This patch is already in Linus' tree and I really think it should go into stable
    as well. You will find this bug in every kernel from the moment cx25821 went
    out of staging.

    I just read Documentation/stable_kernel_rules.txt, so I guess it was enough
    to add a tag "Cc:" in the patch (right?).
    Now I know it :-)

    If I'm doing anything wrong, just yell at me.

    Subject: [PATCH] cx25821: Remove bad strcpy to read-only char*

    The strcpy was being used to set the name of the board.
    Since the destination char* was read-only and the name
    is set statically at compile time; this was both
    wrong and redundant.

    The type of char* is changed to const char* to prevent
    future errors.
