Subject: [PATCH v1] media: lirc: modify the timeout waiting time for the infrared remote control.

When certain infrared remote controls send codes, the kernel side
does not receive them, which is due to a timeout in transmission.
Modifying the maximum timeout time in this area can solve this issue.
