struct mipi_dsi_msg is a read-only structure, drivers should never need
to modify it. Make this explicit by making all references to the struct
const.Acked-by: Andrzej Hajda

Currently the mipi_dsi_dcs_write() function requires the DCS command
byte to be embedded within the write buffer whereas mipi_dsi_dcs_read()
has a separate parameter. Make them more symmetrical by adding an extra
command parameter to mipi_dsi_dcs_write().The S6E8AA0 driver relies on the old asymmetric API and there's concern
that moving to the new API may be less efficient. Provide a new function
with the old semantics for those cases and make the S6E8AA0 driver use
it instead.Reviewed-by: Sean Paul

This commit introduces a new function, mipi_dsi_create_packet(), which
converts from a MIPI DSI message to a MIPI DSI packet. The MIPI DSI
packet is as close to the protocol described in the DSI specification as
possible and useful in drivers that need to write a DSI packet into a
FIFO to send a message off to the peripheral.Suggested-by: Andrzej Hajda

The %* format specifier expects an integer, which works fine with size_t
arguments on 32-bit because the types match. However on 64-bit, size_t
is typedef'd to unsigned long and will cause a build warning.Signed-off-by: Thierry Reding

There are several different models of N116BGE. According to commit
0a2288c06aab ("drm/panel: simple: Add Innolux N116BGE panel support"),
the video timings are for the eDP variant.The clock and htotal values added by that patch are out of spec
according to the datasheets I have seen for the eDP N116BGE (-EA2 and
-EB2).This patch changes the values to the "Typ" values on the datasheet.

Various panels were missing the .bpc field which encodes the number of

the panels can be used with any display engine it must be specified so

do so.Signed-off-by: Thierry Reding

Pull audit updates from Eric Paris:
"So this change across a whole bunch of arches really solves one basic
problem. We want to audit when seccomp is killing a process. seccomp
hooks in before the audit syscall entry code. audit_syscall_entry
took as an argument the arch of the given syscall. Since the arch is
part of what makes a syscall number meaningful it's an important part
of the record, but it isn't available when seccomp shoots the
syscall...For most arch's we have a better way to get the arch (syscall_get_arch)
So the solution was two fold: Implement syscall_get_arch() everywhere
there is audit which didn't have it. Use syscall_get_arch() in the
seccomp audit code. Having syscall_get_arch() everywhere meant it was
a useless flag on the stack and we could get rid of it for the typical
syscall entry.The other changes inside the audit system aren't grand, fixed some
records that had invalid spaces. Better locking around the task comm
field. Removing some dead functions and structs. Make some things
static. Really minor stuff"* git://git.infradead.org/users/eparis/audit: (31 commits)
