On some newer boards, like HVR-930C HD, the information at

available on the device. That causes the probing code to

The crashed member of struct iss_device is documented to be a bitmask,
but a bool doesn't hold that many (usable) bits. Lines 589 and 659 of
iss.c strongly suggest that "unsigned int" was meant (the same type as
struct iss_pipeline::entities). Currently, any crashed entity will be
blamed on index 0, which is unlikely to be what was intended.

Under Xen, vmalloc_32() isn't guaranteed to return pages which are really
under 4G in machine physical addresses (only in virtual pseudo-physical
addresses).  To work around this, implement a vmalloc variant which
allocates each page with dma_alloc_coherent() to guarantee that each
page is suitable for the device in question.

Some fe drivers will have to do additional initialization
in their fe ops.init interfaces when called during resume.
Without the additional initialization, fe and tuner driver
resume fails. A new fe exit flag value DVB_FE_DEVICE_RESUME
is necessary to detect resume case. This patch adds a new
define and changes dvb_frontend_resume() to set it prior to
calling fe init and tuner init calls and resets it back to
DVB_FE_NO_EXIT once fe and tuner init is done.
