Subject: msm: mdss: Fix invalid dma attachment during fb shutdown
|
||
|
|
|
||
|
|
If DMA attachment fail during fb_mmap, all ION memory will get free. It
|
||
|
|
is necessary to reset the fbmem and fb_attachemnt pointer to NULL,
|
||
|
|
otherwise during shutdown will perform another free and causing issue.
