drm/mgag200: Fix driver_load error handling

2015-09-23T22:10:44+00:00

mgag200_driver_load's error path just calls the drm driver's
driver_unload op. It isn't safe to call this because it doesn't handle
things well if driver_load fails somewhere mid way.

Replace the call to mgag200_driver_unload with a more finegrained
error handling path.

drm/mgag200: Fix error handling paths in fbdev driver

2015-09-23T22:10:41+00:00

Set up error handling in mgag200_fbdev_init and mgag200fb_create such that
they release the things they allocate, rather than relying on someone
calling mga_fbdev_destroy.

Based on a patch by Sudip Mukherjee

drm/mga200g: Hold a proper reference for cursor_set

2015-08-10T11:37:20+00:00

Looking up an obj, immediate dropping the acquired reference and then
continuing to use it isn't how this is supposed to work. Fix this by
holding a reference for the entire function.

While at it stop grabbing dev->struct_mutex, it doesn't protect
anything here.

drm/mga200g: Don't grab dev->struct_mutex for in mmap offset ioctl

2015-08-10T11:37:12+00:00

Since David Herrmann's mmap vma manager rework we don't need to grab
dev->struct_mutex any more to prevent races when looking up the mmap
offset. Drop it and instead don't forget to use the unref_unlocked
variant (since the drm core still cares).

drm/mgag200: Use new drm_fb_helper functions

2015-08-06T12:13:04+00:00

Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.

v3:
- Don't touch remove_conflicting_framebuffers

v2:
- remove unused goto label 'out'

drm/mgag200: remove unneeded variable

2015-07-17T06:50:45+00:00

ttm_bo_validate() returns 0 or error. So we can return the value
directly and remove the variable 'ret'.
