From 73858173593c31cb94bce63fe1c24eb803bb04e6 Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Fri, 4 Sep 2015 15:47:43 -0700 Subject: genalloc: add name arg to gen_pool_get() and devm_gen_pool_create() This change modifies gen_pool_get() and devm_gen_pool_create() client interfaces adding one more argument "name" of a gen_pool object. Due to implementation gen_pool_get() is capable to retrieve only one gen_pool associated with a device even if multiple gen_pools are created, fortunately right at the moment it is sufficient for the clients, hence provide NULL as a valid argument on both producer devm_gen_pool_create() and consumer gen_pool_get() sides. Because only one created gen_pool per device is addressable, explicitly add a restriction to devm_gen_pool_create() to create only one gen_pool per device, this implies two possible error codes returned by the function, account it on client side (only misc/sram). This completes client side changes related to genalloc updates.
