+Subject: leds: tlc591xx: update the maximum brightness
+
+From: Jean-Jacques Hiblot <jjhiblot@ti.com>
+
+commit a2cafdfd8cf5ad8adda6c0ce44a59f46431edf02 upstream.
+
+The TLC chips actually offer 257 levels:
+- 0: led OFF
+- 1-255: Led dimmed is using a PWM. The duty cycle range from 0.4% to 99.6%
+- 256: led fully ON
+
