input: cyttsp-i2c-qc: change code path for cyttsp_xy_handler

cyttsp_xy_handler is the function which sends the coordinates
to input framework. In the starting of the function it checks
the mode of the controller. But while going to suspend,
this check is not required, since the controller will
eventually goes to power collapse. So this change will
skip the check if it is going to suspend.

d2: defconfig: Fix bcmdhd fw path

Upon concating revision for bcmdhd, the bcmdhd driver appends the
chip version to fw path. The current fw path can cause issues upon
enablement due to setting the firmware path to:

    /system/etc/wifi/bcmdhd_sta.bin_b2_b2

msm: vidc: cache-flush encoder output buffers after alloc

Flush output buffers explcitly during registering. This ensures
any pending CPU writes (i.e meset to 0 after allocation) are
committed right away, or else this may get flushed _after_
hardware has written the bitstream.

seq_file: remove "%n" usage from seq_file users

All seq_printf() users are using "%n" for calculating padding size,
convert them to use seq_setwidth() / seq_pad() pair.

seq_file: introduce seq_setwidth() and seq_pad()

There are several users who want to know bytes written by seq_*() for
alignment purpose.  Currently they are using %n format for knowing it
because seq_*() returns 0 on success.

This patch introduces seq_setwidth() and seq_pad() for allowing them to
align without using %n format.

vsprintf: ignore %n again

This ignores %n in printf again, as was originally documented.
Implementing %n poses a greater security risk than utility, so it should
stay ignored.  To help anyone attempting to use %n, a warning will be
emitted if it is encountered.

Based on an earlier patch by Joe Perches.

Because %n was designed to write to pointers on the stack, it has been
frequently used as an attack vector when bugs are found that leak
user-controlled strings into functions that ultimately process format
strings.  While this class of bug can still be turned into an
information leak, removing %n eliminates the common method of elevating
such a bug into an arbitrary kernel memory writing primitive,
significantly reducing the danger of this class of bug.

For seq_file users that need to know the length of a written string for
padding, please see seq_setwidth() and seq_pad() instead.

target/rd: Refactor rd_build_device_space + rd_release_device_space

This patch refactors rd_build_device_space() + rd_release_device_space()
into rd_allocate_sgl_table() + rd_release_device_space() so that they
may be used seperatly for setup + release of protection information
scatterlists.

Also add explicit memset of pages within rd_allocate_sgl_table() based
upon passed 'init_payload' value.

v2 changes:
  - Drop unused sg_table from rd_release_device_space (Wei)

f2fs: reduce searching region of segmap when free section

In __set_test_and_free we will check whether all segment are free in one section
When free one segment, in order to set section to free status.
But the searching region of segmap is from start segno to last segno of f2fs,
it's not necessary. So let's just only check all segment bitmap of target
section.
