47348661c4 imx-drm: ipu-dmfc: wait for FIFOs to run empty before disabling
Disabling the DMFC module while there is still data in the FIFOs could
cause the "new frame before end of frame" error state when the DMFC is
enabled again.

98dbeadaf0 imx-drm: fix hdmi hotplug detection initial state
The initial state at boot is assumed to be disconnected, and we hope
to receive an interrupt to update the status.  Let's be more explicit
about the current state - reading the PHY status register tells us
the current level of the hotplug signal, which we can report back in
the _detect() method.

1cf35d4771 mm: split 'tlb_flush_mmu()' into tlb flushing and memory freeing parts
The mmu-gather operation 'tlb_flush_mmu()' has done two things: the
actual tlb flush operation, and the batched freeing of the pages that
the TLB entries pointed at.

This splits the operation into separate phases, so that the forced
batched flushing done by zap_pte_range() can now do the actual TLB flush
while still holding the page table lock, but delay the batched freeing
of all the pages to after the lock has been dropped.

This in turn allows us to avoid a race condition between
set_page_dirty() (as called by zap_pte_range() when it finds a dirty
shared memory pte) and page_mkclean(): because we now flush all the
dirty page data from the TLB's while holding the pte lock,
page_mkclean() will be held up walking the (recently cleaned) page
tables until after the TLB entries have been flushed from all CPU's.

driver has code to blink the led in 7 different ways.
struct led_priv contains an enum LED_STRATEGY_871x variable which is
initialized to SW_LED_MODE1 inside rtl8188eu_InitSwLeds() function.
it means driver is hard coded to use only SW_LED_MODE1 blinking strategy.

The symbol 'r8192_get_wireless_stats' is declared as 'extern'
but it is only used in the local scope. The declaration is deleted
of rtl_wx.h, fixing the conflict with the 'extern' and 'static' scope.

The symbol 'r8192_wx_handlers_def' was fixed of some issues related
