From ab22e77cd3d3073c8cac51b59713ef635678dfbe Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 11 Dec 2015 07:44:40 -0200 Subject: [media] media framework: rename pads init function to media_entity_pads_init() With the MC next gen rework, what's left for media_entity_init() is to just initialize the PADs. However, certain devices, like a FLASH led/light doesn't have any input or output PAD. So, there's no reason why calling media_entity_init() would be mandatory. Also, despite its name, what this function actually does is to initialize the PADs data. So, rename it to media_entity_pads_init() in order to reflect that. The media entity actual init happens during entity register, at media_device_register_entity(). We should move init of num_links and num_backlinks to it.
