Removing the cast should not change anything regarding the code and silences the warning. ../drivers/phy/tegra/xusb.c:421:11: warning: explicitly assigning value of variable of type 'const struct tegra_xusb_lane_map *' to itself [-Wself-assign] for (map = map; map->type; map++) { ~~~ ^ ~~~ Signed-off-by: Nathan Chancellor --- I am not entirely sure if this is the correct solution, especially since I don't have the hardware and I am not too familiar with this code. If there is a better solution, please let me know. drivers/phy/tegra/xusb.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/phy/tegra/xusb.c b/drivers/phy/tegra/xusb.c index 63e916d4d069..11aa5902a9ac 100644 --- a/drivers/phy/tegra/xusb.c +++ b/drivers/phy/tegra/xusb.c @@ -418,7 +418,7 @@ tegra_xusb_port_find_lane(struct tegra_xusb_port *port, { struct tegra_xusb_lane *lane, *match = ERR_PTR(-ENODEV); - for (map = map; map->type; map++) { + for (; map->type; map++) { if (port->index != map->port) continue; -- 2.16.3
