Callback .start_streaming is called once for every queue,
so v4l2_ctrl_handler_setup was called twice during stream start.
Moving v4l2_ctrl_handler_setup to context initialization
reduces numbers of calls and seems to be more consistent with API.

MFC uses two clocks - MFC gate clock and special clock
which is named as "sclk_mfc" in exynos4 and "aclk_333" in
exynos5 SoC. The driver was doing just a clk_prepare on
this special clock without a clk_enable call. As this
sclk is the parent of gate clock, it gets prepared and
enabled along with the gate clock. So there is no need
for the driver to use this sclk. This patch removes the
sclk usage from driver.

dependancy for building the DM365 VPFE MC based capture driver
(VIDEO_DM365_VPFE), This patch fixes this dependency by replacing
the VIDEO_VPFE_CAPTURE with VIDEO_DM365_ISIF, so as when older DM365
ISIF v4l driver is selected the newer media controller driver for
DM365 isnt visible.

and, most of the time, useless.

So, disable them, except if core_debug modprobe parameter

The reason for the crash is that '__efivars' hasn't been initialised nor
has it been registered with register_efivars() by the time the google
EFI SMI driver runs.  The gsmi code uses its own struct efivars, and
therefore, a different variable list.  Fix the above crash by passing
the registered struct efivars to variable_is_present(), so that we
traverse the correct list.

In commit b0de59b5 ("TTY: do not update atime/mtime on read/write")
we removed timestamps from tty inodes to fix a security issue and waited
if something breaks.  Well, 'w', the utility to find out logged users
and their inactivity time broke.  It shows that users are inactive since
the time they logged in.

To revert to the old behaviour while still preventing attackers to
guess the password length, we update the timestamps in one-minute
intervals by this patch.
