Subject[PATCH for stable] cx25821: Remove bad strcpy to read-only char*
From
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: stable@vger.kernel.org" in the patch (right?).
Now I know it :-)

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

Thanks,
Ezequiel.

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.
