Warnings summary:

I have a patch for this, will send after some more testing.

14 drivers/gpu/drm/ttm/ttm_page_alloc_dma.c:1186:2: warning: ignoring return value of 'register_shrinker', declared with attribute warn_unused_result [-Wunused-result] 14 drivers/gpu/drm/ttm/ttm_page_alloc.c:485:2: warning: ignoring return value of 'register_shrinker', declared with attribute warn_unused_result [-Wunused-result]

ttm and kvm are now the last user of register_shrinker that doesn't propagate the return code to its caller, all other callers got fixed in one way or another.

I tried to fix this one too, but couldn't come up with a proper way of unwinding both kobject_init_and_add() and ttm_pool_mm_shrink_init():

ret = kobject_init_and_add(&_manager->kobj, &ttm_pool_kobj_type, &glob->kobj, "pool"); if (unlikely(ret != 0)) { kobject_put(&_manager->kobj); _manager = NULL; return ret; }

ttm_pool_mm_shrink_init(_manager);

Calling kobject_put() after a failed kobject_init_and_add() seemed wrong, and it also appears to be missing a kfree(), so I didn't want to mess it up any further. Added a few people to Cc that touched this file most, maybe one of them can have a look, or they already have a patch waiting to get merged.

Patches for these two got posted a while ago but never picked up. I've merged those into my tree, and plan to forward them to Andrew Morton.

I made patches for these now, will send them in a bit.

Viresh, could you have a look here?

Linus, can you look at this? I don't know which interrupt-parent is the right one here, maybe you can find out from the hardware or some documentation you have.

I finally found the answer here and got a patch now.

I have an older patch that I should send.

I'll get this one.

I need to pick up the right patch here.

I have a patch, will send in a bit.

My patch is in Russell's patch tracker now.

1 arch/arm/configs/omap2plus_defconfig:322:warning: symbol value 'm' invalid for LIRC

I need to address this.
