Simplify probe() by replacing of_match_node() for retrieving match data by device_get_match_data(). Some minor cleanups: * Remove the trailing comma in the terminator entry for the OF table making code robust against (theoretical) misrebases or other similar things where the new entry goes _after_ the termination without the compiler noticing. * Move OF table near to the user. * Arrange variables in reverse xmas tree order in probe(). Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com> --- v1->v2: * No change. --- drivers/input/misc/da9063_onkey.c | 27 ++++++++++++--------------- 1 file changed, 12 insertions(+), 15 deletions(-)
