This backports the upstream commit:
leds: lp55xx: Initialize enable GPIO direction to output
Without it under kernel 5.10 on Asus MAP-AC2200
the LED driver will fail probing:
[ 1.947521] lp5523x: probe of 0-0032 failed with error -22
After the backported fix:
[ 1.873236] lp5523x 0-0032: lp5523 Programmable led chip found

Subject: [PATCH] leds: lp55xx: Initialize enable GPIO direction to output
|
|
|
|
The "Convert to use GPIO descriptors" commit changed the
|
|
initialization of the enable GPIO from GPIOF_DIR_OUT to
|
|
GPIOD_ASIS. This breaks systems where the GPIO does not
|
|
default to output. Changing the enable initialization
|
|
to GPIOD_OUT_LOW.
