[PATCH 5.0 083/146] staging: olpc_dcon_xo_1: add missing const qualifier

[Greg Kroah-Hartman]

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

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

From: Arnd Bergmann <arnd@xxxxxxxx>

commit ae0a6d2017f733781dcc938a471ccc2d05f9bee6 upstream.

gcc noticed a mismatch between the type qualifiers after a recent
cleanup:

drivers/staging/olpc_dcon/olpc_dcon_xo_1.c: In function 'dcon_init_xo_1':
drivers/staging/olpc_dcon/olpc_dcon_xo_1.c:48:26: error: initialization discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]

Add the 'const' keyword that should have been there all along.
