Subject: [PATCH v4 0/2] staging: fbtft: cleanup fbtft_framebuffer_alloc()

Cleanup error handling in fbtft_framebuffer_alloc()

This patchset includes the revert commit for the v1 patch, and the
cleanup patch that is not yet applied.

I have not included the v3 patch ("staging: fbtft: fix potential memory 
leak in fbtft_framebuffer_alloc()") in this patchset, as it has been 
already applied on staging-testing

v4:
- Add a revert patch to remove v1 patch
- Not included the patch that is already applied on staging-testing
- Added Reviewed-by tags

v3:
- Remove a redundant check before calling kfree

v2:
- Change the earlier patch to also handle the error code returned by
  fb_deferred_io_init() and update Fixes tag to point to the commit that
  introduced the memory allocation (which leads to leak).
- Add second patch to make the error handling order symmetric to
  fbtft_framebuffer_release() and also remove managed allocation for
  txbuf as suggested by Andy and Dan.
