staging: fbtft: fix potential memory leak in fbtft_framebuffer_alloc()
[ Upstream commit eb2cb7dab60f9be0b435ac4a674255429a36d72c ]
In the error paths after fb_info structure is successfully allocated,
the memory allocated in fb_deferred_io_init() for info->pagerefs is not
freed. Fix that by adding the cleanup function on the error path.
