There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference.

2017-12-08media: pulse8-cec: print time using time64_tArnd Bergmann
The firmware timestamp is an unsigned 32-bit value, but we copy it into a signed 32-bit variable, so we can theoretically get an overflow in the calculation when the timestamp is between 2038 and 2106. This changes the temporary variable to time64_t and changes the deprecated time_to_tm() over to time64_to_tm() accordingly. There is still an overflow in y2106, but that is a limitation of the firmware interface, not a kernel problem.

sub-devices When matching and registering a sub-device from a sub-notifier use the v4l2_device from the root parent notifier. Using the v4l2_dev stored in the sub-notifier itself is incorrect as it might not be set. This can be demonstrated by unbinding and rebinding the adv748x driver and observing that it fails to probe due to the check !v4l2_dev in v4l2_device_register_subdev(). # echo 4-0070 > /sys/bus/i2c/drivers/adv748x/unbind # echo 4-0070 > /sys/bus/i2c/drivers/adv748x/bind adv748x 4-0070: chip found @ 0xe0 revision 2143 adv748x 4-0070: Failed to probe TXA adv748x: probe of 4-0070 failed with error -22 Looking at the commit which adds sub-notifiers to V4L2 it looks like this is the intended behavior of the original commit.

2017-11-30media: rc: partial revert of "media: rc: per-protocol repeat period"Sean Young
Since commit d57ea877af38 ("media: rc: per-protocol repeat period"), most IR protocols have a lower keyup timeout. This causes problems on the ite-cir, which has default IR timeout of 200ms. Since the IR decoders read the trailing space, with a IR timeout of 200ms, the last keydown will have at least a delay of 200ms. This is more than the protocol timeout of e.g. rc-6 (which is 164ms). As a result the last IR will be interpreted as a new keydown event, and we get two keypresses. Revert the protocol timeout to 250ms, except for cec which needs a timeout of 550ms.
