[PATCH v2] phy: tegra: Remove self cast in tegra_xusb_port_find_lane

From: Nathan Chancellor
Date: Sun Apr 01 2018 - 07:04:21 EST


Clang warns about casting variables to themselves because it is rarely
necessary. 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++) {
~~~ ^ ~~~

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.
