From: Jiri Slaby Date: Sun, 14 Feb 2010 20:36:25 +0000 (-0300) Subject: V4L/DVB: V4L: dvb-usb, add extra sync to down-up input events X-Git-Tag: firefly_0821_release~9833^2~3102^2~65 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=18718c96e3e10e6b821d32c50adde9fa5cc6565a;p=firefly-linux-kernel-4.4.55.git V4L/DVB: V4L: dvb-usb, add extra sync to down-up input events Userspace is allowed to coalesce events between SYNCs. And since the code emits UP right after DOWN for the same key, it may be missed (up+down=nothing). Add an extra sync in between UP and DOWN events to disable the coalesce.
