Subject: [PATCH] [media] s5p-jpeg: Fix crash in jpeg isr due to multiple
interrupts.
In case of corrupt images, multiple interrupts may occur due to different
error
scenarios.
Since we are removing the src and dest buffers in the first interrupt itself,
crash
occurs in the second error interrupts.
Disable the global interrupt before we start processing the interrupt avoid
the
crash.
Disable System interrupt in isr to avoid the crash below.
Unable to handle kernel NULL pointer dereference at virtual address 00c8
