Subject: [PATCH] staging: olpc_dcon_xo_1: add missing 'const' qualifier
Date: Mon, 4 Mar 2019 20:42:33 +0100 [thread overview]
Message-ID: <20190304194242.765398-1-arnd@arndb.de> (raw)
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.
Fixes: 2159fb372929 ("staging: olpc_dcon: olpc_dcon_xo_1.c: Switch to the gpio descriptor interface")
