Subject: [PATCH] leds: pca963x: Add missing initialiation of struct led_info.flags

drivers/leds/leds-pca963x.c: In function ‘pca963x_dt_init’:
drivers/leds/leds-pca963x.c:303: warning: ‘led.flags’ is used uninitialized in this function

Only the name and default_trigger fields are initialized.
Other fields (currently flags only) contain random stack data.
Pre-initialize the led structure completely to fix this.
