Subject: [ 21/73] cx25821: Remove bad strcpy to read-only char*

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ezequiel Garcia <elezegarcia@...il.com>

commit 380e99fc44d79bc35af9ff1d3316ef4027ce775e upstream.

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.
