After subsystem restart is completed, driver will try to restore the
internal clock state to state before subsystem restart. In some cases,
it is possible that the internal clock state is not restored properly.
This causes the internal clock to be off when it is expected to be
turned on. Fix this issue by making sure the clock states are restored
correctly post subsystem restart.

the HW_EN2 pin control enable configuration for LDO 18 at
runtime. When this regulator is enabled, LDO 18 output is
enabled whenever HW_EN2 (i.e. PM8994 GPIO 11) is driven high.
When this regulator is disabled, the state of GPIO 11 is ignored.
This regulator can be used to support WLAN antenna sharing where
the WLAN chip is connected to GPIO 11 and drives it high whenever
RX or TX is active.
Also update the voltage constraint range to allow values from
2.7 V to 2.9 V.

Liping Zhang spotted a race between tcp_nuke_addr and tcp_close
that can cause a crash. If a userspace process calls tcp_close
on a socket at the same time that tcp_nuke_addr is closing it,
and tcp_close wins the race to call lock_sock, it will call
sock_orphan before releasing the lock. sock_orphan sets the
SOCK_DEAD flag on the socket and proceeds to close it, eventually
calling inet_csk_destroy_sock. When tcp_nuke_addr gets the socket
lock, it calls tcp_done. But if tcp_done sees the SOCK_DEAD flag,
it calls inet_csk_destroy_sock as well, resulting in a double
free.
Fix this by checking for SOCK_DEAD again after lock_sock
succeeds. Eric had already pointed out that this could be a
problem in b/23663111, so there was already a TODO in the code
for this.

Debug data read was not handling the buffer overflow case when
the data to write is greater than PAGE_SIZE. This resulted in
calling the hardware for new data multiple times.
Returning success when buffer overflowed will cause the sequence
traverse function to call again with a new buffer with increased
size. This process will go on until the buffer size is big enough
to hold the data. But limits data read function couldn't distinguish
if the call is a retry or a new call and will initiate a new data
fetch from hardware and re-populate with new data.
Modify debug read interface to immediately return success when
overflow happens. The debug read function now can distinguish between
a sequence retry call by retaining the data buffer in a static if
overflow happens. When called again, debug read now will avoid
calling the hardware for new data and instead will populate the new
sequence buffer with the previously fetched data.
