Subject: [PATCH] arm/boot/dts/overlays/mipi-dbi-spi: fix default
brightness (#5442)
There is an off-by-one error in the default brightness for the PWM backlight
in the MIPI DBI SPI overlay that produces the following message in the
kernel logs:
pwm-backlight backlight_pwm: invalid default brightness level: 16, using 15
The value is 0-based, so the max brightness is 15, not 16.
