net: tcp: check for SOCK_DEAD again in tcp_nuke_addr
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.

msm: mdss: Correctly reset the ad_events count
Reset the ad_events count in the AD ioctl instead of ad_setup().
There are some time delay between AD ioctl and ad_setup, which is
part of the display commit path, so if we reset the ad_event count
in ad_setup, then it is possible that user space reads the ad_events
sysfs node after the AD ioctl but before the ad_setup(). In that
case, user space may get the incorrect ad_events count, and cause
the gradual AD off fail.

msm: mdss: add multiple register support in ESD check
Current implementation cannot support multiple registers
in ESD check, and it does not work for many cases. For
example, some panels need check multiple registers to get
its status, and some panels might return several possible
values for one register read.
To support this kind of behaviors, a new property in dtsi
is added as "qcom,mdss-dsi-panel-status-valid-params" which
specifies the valid value length we should check in the
payload returned by panel, and the payload length panel
should return is specified by the property "qcom,mdss-dsi-
panel-status-read-length". "qcom,mdss-dsi-panel-status-value"
is also extended to an array which specifies all the possible
return values from panel.

msm: mdss: make sure backlight is off during suspend
The backlight of the display panel will not get turned off during
suspend if there are no display commits between suspend/resume
since allow_bl_update will only be set to 'true' after first
valid display commit after resume. This is possible for power
off charging use-case where there will be only one display
commit initially and later just the content of the buffer gets
updated without anymore display commits across suspend/resume.
Make sure the backlight is turned off during suspend by
explicitly setting allow_bl_update to 'true' before trying to
set the backlight to zero.

msm: mdss: move used pipes to cleanup list on overlay free
Avoid moving pipes to destroy list during overlay free based on
the pipe play count as it might not give the actual information.
The play count is set to 0 for all new or config changed pipes
during the validate call. And if we get a fb_release_all request
right after the validate, it would indicate an inconsistent state
for the play count. Instead, move the used pipes to cleanup list,
so that the NULL kickoff would handle the pipes to be unstaged
and destroyed.
